Just joined the "club" today and am looking forward to some great advice. I have had my 54 gallon bow front tank for about 8 years now. I had a Puffer for about the last 2 1/2 years and it recently died. My question, I bought a Volitan Lionfish about 4 months before the Puffer died, and within a couple of weeks, I also lost a Tomato Clown. There never seemed to be a problem with the mixture of fish, but both the Clown and the Puffer seemed to have become blind and disoriented for several days before their death. Actually the Puffer seemed to recover and then suddenly died. After that I missed my Puffer so much, I purchased a cute little Burr Fish. It also died the same way within about a week. Do you think the Lionfish is killing off my tank? I do have an eel left that doesn't seem to be having any problem and the Lionfish is also quite healthy. Help! If I have to try and trade this guy in, in order to have other fish I will do that, or maybe you can tell me what he is compatible with from your own experience. My books said he was compatible with my Puffer, but maybe not. Thanks! Sheila
