Hi craig! (I found out why I lost site. a "," was in the link name...hehehehe) @Cindy - I also have a Hippo and it's a wonderful active creature. I lost all clowns that went with it and a Lamarck Angel all because I did not QT. Best bet is to QT before introducing a fish. But I really seldom do this. Anyway, the Hippo and a Fairy Wrasse, a FoxFace Rabbit and a Lemon Damsel all surivived the ich infestation. I simply used garlic and maybe someday soon will add a Lysmata Amboinensis. These two (garlic and cleaner shrimp) can help us in a tank which is already established and is having a bad ich day/s. Good luck. If the hippo is feeding well (you do feed your hippo 3x a day in small portions right?) and their food treated with garlic, the fish will do fine. Btw i use garlic oil in gel capsules because they are easier to mix with food. Puncture capsule and drip oil into the food.
