Can these fish be together

Question

Ok i have asked this question alot but if i have 38 gallon aquarium and i was getting 4 pictus catfish could i fit 1 firemouth cichlid and 2 silver dollars. Would that be ok?

Answer 1

The cichlid would need a bigger tank. The pictus would need a bigger tank, and can get to be 9 inches or more.

Answer 2

is the tank a regular rectangular shape? or is it hexagonal? in a hex tank, none of them would work. in a regular tank the pictus and silver dollars would be fine, but the fire-mouth will need a bigger tank,
