Hi guys, I am setting up a new 55 (Petco's $1/gallon) and am wondering if I can put my 4"-5" Sveni with some mbuna (mainly yellow labs and peacocks)? I currently have him with a Polleni and they go back and forth. With the Africans I have a firemouth (will be moving), a red tail shark that's giving them hell, a Tropheus Duboisi (which is doing quite good actually) one lone tiger barb (it help kill the other tiger barbs in the tank) & some fish that came in with a group of Jack Dempseys. For some reason my pike is not putting on any size since I got him over 6 months ago, even though he eats like a pig. He doesn't seem to have parasites, from what I've read. Thanks in advance for any help.
