Help!!!!!!!!!!!

I am leaning back to what the original guys thought. This sound more like vibro infection. The leasion look exactily like the photos of vibro from the Aug/Sept issue of Coral.

You could try to QT and treat the remaining fish with tetracycline but at this point there isn't much you can do other than getting the dead or dying fish out of the tank as fast as possibly.

Sorry for losses.

 

after everyone's input i'm still sticking with what i mentioned earlier. as for what type of parasite was brought into your aquarium, i'm unsure. it doesn't seem as though you've been able to determine which fish was the culprit. my advice...don't buy fish online, you never know what you're going to recieve. go to your local lfs, find a fish that you fancy and carefully examine the fish for lesions, spots, etc. it's the only real way to be sure that the fish is healthy, not to mention you know what you are purchasing. beyond that, (in the immortal words of matt) "go slow"...never add too many fish at one time, more than likely it will be too much stress on the system. in the meantime keep a careful eye on the remaining fish in the tank...if you are at all uncertain of a particular fishes health, remove them immediately and (hopefully by this time) set up your quarantine tank so that the "disease" doesn't spread any further. HTH.
