I have mine now in an aggressive tank. I previously had them in a tank with nanos, Myrnae, gold rams, German rams, and rainbow cichlids.They wasn't aggressive to the others, but the HRP attacked each other and the rainbow cichlidsAre they good community fish? I want to get them with a harem of german blue rams, 6pcs perhaps? Do you think they will be OK in a heavily planted tank? I am planning to return my rainbows and my t-bars and then rescape my tank adding the less hardy plants. I already have the rocks and the driftwood in there. Fingers-crossed I am hoping they (the HRP's) would let the anacharis, cabomba, the bacopas and the rotallas thrive.
