I love my clown knife......actually love all my fish but he's gotta be my fav!! As far as fav non-owned fish got to be a RTC just wish I had room for one!!!
3 tanks so 3 sets of favorites: first up is my african tiger pike because it is the only one i have ever seen with red fins and will only eat live food or market shrimp, then comes all of my bichirs because they are the reason i got a tank in the first place, then my cobra pike and plecos come next, followed by my now juvie collection which has 5 pbas : mono's i think, and a 4-5" tsn catfish, i love all of my fish for different reasons which would be a list too long to write but i am mostly a predator fan because i like to watch the food chain in action.
