Purple Firefish

[anmith]

I have two orange tailed firefish in a 155 gal tank, along with several(5) tangs, a Royal gramma and a Marine Betta. I purchased two purple firefish that I kept in a 55 gal tank. I have read that you can keep pairs of firefish in larger tanks peacably. Well, one of the purple firefish has sinced passed away. What are the chances of the remaining one surviving in the 155 the other two orange firefish?

Problem #2

I have three oscellaris clowns in the 55 gal tank also. About two months ago, one of the clowns could no longer keep himself upright, always on his side at the top of the tank. He has not recovered, there are no visible signs of trauma, and he still eats. Now one of the other clowns is begining to show the same signs of unbalance. What's going on here, these are tank raised clowns about one and a half years old? The tank has a few pieces of live rock (3+ years) from my main tank.

I currently have two Nemateleotris magnifica and one Netmateleotris decora (2 red, 1 purple) in my 75G. The N. decora sometimes hangs out with the N. magnifica, but mostly just ignores them. I think I will end up getting another N. decora because they are almost always seen in pairs in the wild.
Regarding your clownfish problem. It almost sounds like they have damaged swim bladders. Perhaps it is due to some type of infection. Fish can sometimes survive and recover if this happens. Not sure what, if anything, you can do to treat it except good care (i.e. stable water conditions, feeding, etc.)

I also have 1 decora with 2 magnifica. They get along very well and hang together as a trio quite a bit of the time. Can't help with the clowns. Never had to deal with a problem like that.
