There are dwarf pikes you could keep in a 40 breeder, maybe smaller. Then there are pikes in the Lugubris group that get well over a foot and would need at least a 125. So the answer really depends on the species you want to keep.HI I really like pike cichlids and was wondering what tank size for 1 pike
Then something in the saxatalis group will work. What kind of fish are u considering for a carnivore fish?I was thinking a 75g natural planted tank with one carnivor fish and feeder fish and shrimp like in the wild
