I agree, a bit too red. I'm going to swap out the three parrots soon and add a buttikoferi or another flowerhorn. A GT is a good suggestion, thanks, but it may be too wimpy. I'm affraid a dempsey would get his ass kicked.
Tanks is 350g filtered by a big wet dry; 50% water changes every 10 days to2 weeks. A dedicated Mag 36 pump hidden in the plants makes water changes easy. Switch it on for 10 minutes with hose out the window, and then pump in new water from my house's spiggot.
