I have a 40 gallon and and i have a red devil cichlid,the problem is i want to add either a maxijet or aquaclear powerhead.Should i do it.the real problem is i dont want to take up tank space by adding a powerhead but then again i really want one in the tank.Will a powerful powerhead take up space.When i say powerful i mean either a maxi jet 900,or a aquaclear model 50.
