I was at my LFS and I seen a tank of "Assorted Pike Cichlids" I was wondering what is the average size? and also can I add one with my Green Terror, Convict, and Syno Catfish in my 55g?
depends on what group of crenicichla the pikes are from. lugubris pikes probably get on average in the 12-14 inch range and those wouldnt be good for a 55. saxatilis pikes probably stay in the 10 inch range on average and that might work. dwarfs are gonna be much smaller at 4-5 inches and probably wouldnt work well the the gt.
try to get some pictures of them and we can help let u know what they are.
