I had, had my tank set up for 10 months before I got my blue hippo. When I got him he was only maybe an inch and a half long, I bought him for $40.00. My LFS sells them for $80, so I went with the internet. I have a long 55 gallon, in which we have a 75 here at the home and are in the process of buying new equiptment for it to upgrade, but I have had him for about uhhh 2 months or shorter, seemed fine at first, but like everyone said, he carried Ich with him, not having the quarintine tank set up anymore because I had gave it to my sister, I had Ich in the DT. Him being the last fish we were buying so that it wasnt over crowded until we got the other tank set up, we made the mistake of not taking the time to Quarintine him being the last one! BIG mistake I know. But I got a medicine called no sick fish, and it was cured!! Everyones doing great! No problems. Hes happy and healthy as can be! Hasnt grown any yet really, still a little bugger!! But thats my sucessful story on the keeping of the blue hippo tang! Beautiful fish! :happyfish
