I had one kel from his second batch that really was timid,it would stay behind the plants most of the time.Then I was able to get a nice one from Sharkaquarium this past July and it is much more outgoing and I've gotten it to eat cut up smelt.Kelberi are like the Datnoids of Cichla but they are my favorites.
Channa = The Man ( or The Kid). Do you still have any kelberi left? I know you have kept every fish under the sun at one point or another!
