powerheads for cichlids

[Ripdevil]

i have owned piranhas in the past and now am dedicating my time to a dovii, a RD and a GT, all in seperate tanks.

i know the piranhas reacted well to the poweheads, is there any need for ones with the dovii or RD.

dovii is in a 125g, and RD in a 55g

any thoughts? thanks
