I'm getting 180 gal tank, I want a bunch of p's. Rhombus sound tight but could I get 5 or so in a 180 or would that not work. want rhoms or caribe, rather have rhoms but don't know. what do you guys think? could i do 5 rhoms in a 180?or would it not work because i've heard more than one rhom is a bad thing cause they'll mess with echother. please help.
