I have a running 180 gallon tank for sale with tons of live rock covered in kenya tree and green star polyps. It's a super cool tank for fish and cool critters, but not one I'd suggest for serious corals or reefing, as there are some majano anemones in there. There is sand/crushed coral substrate and a number of fish, including a yellow tang, blue tang, clownfish, filefish and a few others. It includes LED lights with timers (cheap China version, seems to grow softies), return pump, sump, new $500 skimmer and all the other stuff it needs to run and maintain a healthy little system. Dimensions are 6'x2'x2' and has a wood stand. This has literally been running for 10+ years. I bought it three years ago from someone that had it for 7+ years. This thing is big and a pain to move. I paid an aquarium company around $300 to move it (Aquatropics I think) and it was definitely worth it. I'm mostly looking to get the creatures a good new home and find someone willing to move the tank, as I'm currently out of state and can't help. I'm asking $350 OBO. I paid $1000 for it three years ago and just put in the new skimmer, so not a bad deal, even after paying to move it. I've got an Apex system on with with wave pumps I'm selling separately, but I'll make a deal if you want to buy both. Message me with questions or if you'd like to make an offer.
