Hi, I'm new to the hobby.  I have a 55 gal. w/60lbs LR and 30lbs LS.  I have about 240 W PC lighting w/Actinic & white light.  An Emperor 400 filter and tank has run since July 2003.  About a dozen snails and a dozen hermit crabs (red and blue legged).  I just lost a lot of fish due to Ich which was followed by Marine Velvet. Dead I have waited about two weeks after dosing with Iodine and garlic.  My surviving fish are: 1 Yellow Tank, 1 Purple Firefish, and 2 Green Chromis.  I just added 2 Clarkii clowns (got a great deal on them so I couldn't pass them up.Big smile)  All fish a juveniles except the Tang who is adolescent.  I also lost my golden head sleeper goby to MV.  Now, I am wondering if I should get a few shrimp gobies (And how many, and if I should get a shrimp as a symbiont) or should I go with another golden head sleeper?  What works for keeping the sand stirred?  My last sleeper put a LOT of sand ALL OVER my rocks , which kept the good algae down too!

I hope this doesn't come across as harsh, but my advice is to Stop adding fish! Especially if you just added two recently. Every fish you add after the outbreak of Ich and Marine Velvet, the more your livestock (present and Future) have the potential to become stressed out, and infected with parasites. Give your fish a chance to recover and fight the parasites. If you find that you're having problems like Ich and Marine Velvet outbreaks, then something in your system is out of whack and you need to get it figured out before you add anything else to your tank. Garlic has helped my livestock to keep them healthy enough or immune enough to fight off the disease before it becomes a problem, but there is no substitute for a healthy environment in your tank. If you have algae growing out of control, then you more than likely have a different problem, and you need to figure that out too. In the meantime, my advice is to add more hermits and clean-up crew. But don't add more fish until the problem is fixed.

Ich and especially Marine Velvet, can take longer than a month to run it's life cycle. Marine velvet is especially difficult to get rid of.

I speak from experience on this one. I lost plenty of livestock because I was overanxious to add fish to my tank. In every situation, I was losing fish because water conditions/parameters in my tank needed to be corrected.

Hope this helps.

Thanks Ryan.  I did not realize it took MV so long to run its course.  Have you got any suggestions on how to tell what could be out of whack?  I have taken water samples to several LFS and all samples are ok.  They tested Ammonia, Nitrate, Nitrite, PH, Phosphate, Iodine, Strontium, Magnesium, Calcium, Alkalinity.  I have all tests mentioned at home except Iodine, Strontium, and Magnesium.  My SG is always around 1.023 with water temp at 76 degrees F.  I do a 10% water change monthly.  I keep my hands and arms out of the tank except when having to put a coral back after my crabs or snails knock it off or if I have to clean the filter screen, then I use rubber gloves that have been rinsed off with fresh water.  I do not use ammonia to clean any of the glass.

I'm going to agree with Ryan and suppor the "don't add" theory.  In fact why not wait 4 or 5 months?  I would like to see pictures of the tank, if that is possible.  I think that will help others (and me of course) to make better recommendations.

When in doubt.... do nothing and wait.

I think you're doing all the right things... Just be patient, and don't add anything for a little while. If nothing else is wrong in your tank, with Water Params and such, could just be that your fish are stressed out, either from being added to the tank, or having other fish added to the tank. It would be good to know as much as possible about the tank as well... One thing that I'd be interested in is what your lighting periods (on/off) are... If your lights are on for longer than necessary, that may be cause for concern... This is a common mistake for beginners in the hobby, as they want to see the tank as much as possible during the day... When I first started my tank, I used to have my lights turn on in the morning before I went to work, and then not have them shut off until after I went to bed. I lost a few fish this way, as it screwed up their eating habits, stressed them out, etc. Try to make it as natural for your inhabitants as possible. That includes lighting, etc... Also, make sure that you are acclimating your fish as close to the recommended procedure as possible to avoid them becoming overly stressed... I know, there's a lot to learn...

Here are four pictures I took tonight.  I have a 10 gal. tank on the right side of my 55, so it is hard to get a picture from that side.  The tank(s) sit in a room with no windows.  What daylight gets in is reflected or indirect.  My actinics are on from 12:00 to 10:30 p.m., my white lights are on from 1:00 to 9:30 p.m.  You can see a couple of snail trails on the front of the tank.  There is a little green and a little red algae on the glass tonight.  It will probably be gone tomorrow.  The snails do an excellent job!   I am having a hard time with the be patient and wait part of this hobby.  When I lost the fish earlier it seemed like that happened quickly (One night=all is well, next night=fish swimming funny, next night=dead fish).  For some reason I have not seen any copepods that I know of.  I have found some little fish (about 1/8th inch long in the LR) that are definitely light shy, but that is all!  I have one feather duster that I did not buy, and one Chiton (I think that's what it is), and a bunch of red sponge.  Recently my BTA (green) split into three, so now I have the BTA's, one Seabae anenome, a moon coral, some yellow polyps, some star polyps, a Xenia (My favorite), three green mushrooms (I started with two), and three button polyps from last month's WMAS fragging. a Candy cane and a Sun polyp.  We bought two Emerald crabs, one has mutated to a huge monster, the other has pretty much remained the same size.  All my SPS, snails, crabs, and Tiger cucumber have grown more than I expected.

Anyway, here the pics.  If anyone has hints on how to get better pics, let me know.  I am no photographer!

The last pic (Bottom) is why I asked about getting something other than a Golden Head Sleeper.

Thanks, that helps a ton.  Here is my opinion, I hope others jump in as well. 

New tank.  Looks freshly set up.  Very little biological filtration (in terms of corals and filters).  Also, how deep is that sand bed?  Maybe it is just covered with the tank frame or stand, but it looks like it is 1" deep.  My feeling now is that your tank is appropriately stocked for now, and I think a sleeper or any other goby would be more destructive than helpful.  I wouldn't add anything, because I would want to give the pod population a chance to grow.

Right off the tank looks good to me, it just looks new. Hope this helps.

I agree with Adam. Looks good, but the Biological filtration needs a chance to stabilize. You could add another 2-3" of sand (either live, Utah Oolitic, or caribsea aragonite) and seed the new sand with your current live sand. (Just don't cover up all of your live sand at once...)

Keep up the good work. And keep posting your progress.

Thanks a ton guys!  I was wondering if I should add some more sand or not.  What I have is at least 1" and in some places (In the back where you can not see) it is about 4" deep.  What should I aim for as far as depth?  I have been afraid to add more filter feeders.  I forgot to mention I do have one scallop in the back (since he stays back there I tend to forget about feeding him and counting him, you know, out of sight-out of mind).  Should I add more biological filtration to the tank or wait?  I have also been trying to get a regium set up under the stand (Just a 10 gal. unit), but need some help with how much flow and I want to know if 10 gal. for a 55 gal tank is adequate.

Thanks again!

Reading this thread was a BEAR!!
Rstruhs, Could you please edit your post box with the pics by hitting the "Enter" key after each pic text link so that they will line up vertically instead of horizontally?
Thanks.

I also see eveidence of a new tank that has too many fish and not enough coral and algae growth. Please don't be alarmed at my straight forward manner. I intend no offense.

Coral are excellent for stabilizing a reef tank. And why is that? Because they harbor Zooxanthellae algae in their tissue. Algae eats nutrients/purifies the tank water. Because they capture and eat the free-swimming stage of the ich parasite. Because they usually come on good LR that was kept submerged which allows sponge and other helpful organisms to make it to your tank in half decent shape. These are just some of the reasons.

Give it some time and some coral and some algae. In it's current state I'd give it four months before adding any more fish, not even replacements. If you get it going with coral and algae, the four months becomes meaningless.

Actually there are probably few people that use those long rubber gloves.
The older it gets with more coral and such, the more it can handle clean hands and arms. This may surprise some people but if you wash hands and arms with soap, rinse several times and dry with a clean towel you'll have "No worries mate."

You asked for comments. I hope this wasn't too much info.
P.S. Bristleworms are our friends!

Thanks Mark, I was wondering what I needed to do to get the pictures and text narrower!

BTW guys, I am not one that gets offended easily.  I appreciate straightforward honest answers/feedback.

Hi, rstruhs! We had a 10 gallon sump on our 55 and it worked great! We put a regular plant light bulb on it and it grew tons of calurpa. The cool part with a sump is, you can put a deep sand bed there and have even more biological diversity. Crawly things grow like crazy in a protected sump.
   If you ever decide to move the tank or get a different one, you have a already established deep sand bed! We moved our 10 gallon sump to our new 180, moved all the 55 gallons stuff and everything did wonderful!
The flow can be slow so it doesn't mess up the sand. We just had a small power head in ours, with just a tube running to it from the tank. One thing I did learn is, you need 2 just in case a snail gets sucked in! If you want to make an overflow out of acrylic, I've got some leftover pieces. It's really easy! I've got some spare tubes ,too.
Once you get the refugum going, you can take the emporer to the "swat" meet!
You're tank looks way cool!

I guess your main question is about a sand sifter other than a goby. I use a sand sifting starfish and I am very happy with it. It keeps the top inch or so very clean.
However, it will eat all of the life in your sand if let it. I have a large sump with 3 to 4 inches of sand, so I don't mind if the sand in main tank is kept completely clean. It will constantly be replenished with critters being pumped up from the sump. I also have my rocks placed in a manner in which it can not get to the area behind the rocks, which keeps that part of the sand alive.
The starfish works wonderfully for me in tis situation.
A word of caution, it sounds like your only form of filtration is the Emperor. The sand most likely is also doing allot for you (not really the sand but all the stuff that lives in it.) If you choose the route of a starfish, then you will probably need to increase filtration, with maybe a skimmer or refugium. As you will lose some of the filtering capacity of your live sand bed.

Anyways, that is a lot of rambling.
Good Luck,
Rich

Cyanobacteria, that slime algae stuff is not all bad. It is one of the major algal species of the world, producing an unusually disproportionate amount of the world's oxygen.

Usually a reduction in feeding and/or an increase in direct water movement and/or some kind of herbivore (hermits, snails, goby, sea star) are the best options for reducing cyano. There are some chemicals that can temporarily eliminate it but most of those products also kill the good bacteria.

Here is some that has come and gone over the past year. It's in a receding stage right now. It's actually kind of a pretty bright green so if anyone wants some just let me know. It may outcompete the uglier stuff.

Mark,

Nice picture!  Would you mind sharing what settings you used on your camera and what light(s) was/were on in the aquarium at the time?

All,

Just to keep you up on what is happening in my tank, one of my clowns died sometime during the day.  When I left for work, all noses were swimming.  When I got home I found one clown down by some rocks on the side of the tank and next to the glass.  It was wedged in there pretty good and looked like its' left side had been smashed.  I do not know what happened, however, I do know it was not MV or some disease.  It had not been picked at yet, and like I said the left side was damaged.  Its' eye had been smashed, its' gills were disfigured, and it appeared to have a vertical cut just in front of the gill slit.  Could I have an errant crab?

Hmmm... Sometimes when fish get stressed, they swim erratically all over the tank, is the damage consistent with smashing into rock, or does it appear to have been attacked? Especially where you say it was wedged into some rocks... Were the two clowns you bought a mated pair, or has one of them been chasing the other one around the tank for the past few days. I'm wondering if one of them got chased into a corner by another fish or something... Anything is possible though... Look for hitchhiker crabs? Maybe. But I doubt it. Crabs usually only attack a fish like that if it is sick, or caught someplace. I think of them like Vultures... They don't attack anything until it is sick, or dead. That's not always the case, but more often than not it is.

Ryan,

"is the damage consistent with smashing into rock, or does it appear to have been attacked?"  I am no expert by far, but it looked more like an attack.  It was just on one side though, if it were a crab is should have been marked on both sides, if it ran into rocks for some reason it seems like the damage would not have been so noticable.  I should have taken a picture.  They were juveniles, however, they were sharing the same anenomes. they would both move from one to another.  I have four for them to play in, so they kept busy trying to please all four.

If the other clown dies in the next few weeks I will still have to consider Marine Velvet strongly.  Although it did not appear to have been infected/affected?

The lights in the pic above are just the VHO of the aquarium.
The Sony 3.x mp camera was set on "Macro" I believe. The trick is to take pictures at varying distances until you get lucky with the right focus. The screen on my digital camera is so small it's hard to see if a view is in focus so I take several shots.

I agreee with Ryan, the damage to that fish most likely is the result of it's dying tremors. Other damage would be the result of organisms, including fish, picking at it after it died.

Just an udate on the tank.

My other clown died shortly after its' friend.  All the other fish are doing fine.  I have been watching for "critters" at night and have seen a lot of little crawling things.  Some look like fleas, others are about a 1/4" long.  I have even seen a couple of bristle worms.  There are some long, thin tenatacles that come out at night from some white tubes on the rock.  I do not know if they are good or bad, but since they are so little, it probably does not matter.  There are also two forms of Chiton in the tank.  One has a partial shell, is long and fast, the other is almost perfectly round and very very very slow.
