What can I expect the behavior of a belly crawler pike in a 55 gallon. Tankmates are a 10 inch commen plec and a 3-4 inch jewel cichlid. Possibly have 4 pictus cats with it as well.
They can be very agressive, especially when other fish come into their territory. I would definitely have enough hiding places for the pike and also the pictus cats.
EDIT: make sure whatever you put in there with it is not smaller than it's mouth, or they will become an easy meal.
