 Topic: question about blennies...
Posted: February 04 2009 at 1:26pm |
I want a lawnmower blenny. I've ALWAYS wanted one. But the largest tank I own is 20 gallons. I assume that's too small for a fish that could grow to 5 inches. Is there another blenny, or fish that looks like a lawnmower, that'll sift the sand or eat algae, and won't slowly DIE in such a small tank? Bought a scooter -- he lasted a month.   I hated that I didn't look up the correct information in advance of that purchase. So that's why I'm asking now. Any recommendations on such a fish?

Hmmm, maybe I'm wrong, but I think most people would tell you that a lawnmower blenny is fine in a 20 gal tank. I'd feel confident in buying a LB and I think you'll be fine.

Im not sure what problems you had with that scooter blenny but I have had mine for a long time and he is really easy to keep happy. They dont grow that fast so even if you get a small one he should be ok in there.

Disagree on the scooter. They aren't actually blennies but dragonets, and I wouldn't be quick to recommend them in small reef tanks.

they eat small crustaceans, and my tank didn't support enough copepods and amphipods to keep the scooter full.  And he wouldn't take brine shrimp.  But the lawnmower, they're algae munchers right?  Or are they sand sifters?  Or both? And if the algae runs low, can I add nori to the tank?

I see your point about eating pods. I put mine in my tank when it was first new. before I had a large population of pods and he eats bloodworms. He doesnt touch the brine shrimp but loves the worms. That may be a personal choice of his. Did you try bloodworms?

Adam may be right but I think 20 gallon is a little small for a lawnmower blenny. I would get one of the smaller herbivorous blennies such as a Tailspot blenny for a tank that size.

What if I had TWO tanks that I could switch him back and forth
between? I've got a 16g that is ripe with algae and has a 2-1/2"
thick sandbed. He could go to town in there and wouldn't be
hungry for a long time. And not so big a tank that I couldn't
catch him when needed to transfer him to the other...... dumb
idea?

They are very difficult to catch and you would probably tear apart the tank trying to catch one. If a Lawnmower Blenny is what you really want then I say go for it. You can supplement their diet with Nori.

Last I checked Lawnmowers don't sift sand... I've had one for well over a year, if they do sift I am taking mine back as defective 
How about an eyelash blenny? (not the Chestnut Eyelash Blenny)
I have one of these guys in my frag tank. He is 2-2.5" long and eats well. (also leaves little kiss marks on the algae on the glass, like a lawnmower blenny) I got mine from Marine Aquatics, 6+ months ago.
Edit: these guys don't sift sand either.

CrimsRayne is right. Blennys are not sand sifters.

I just got one (LB) for my tank last week and gave it to my son as HIS first fish in the tank for doing a good job at school. He named it Trimmer and we all love it...it has these cool "fangs" and "eyelashes" and is about 3-4" long. They have so much character all perched up on the rocks with their eyes looking all over.
Click the link below and you might see him once and a while ;) I just got it set up on the web...pretty cool...
