Hey everyone have a chance to get some grammodes tomorrow, was wondering if a 90 gallon tank is big enough to support one male. Guy told me the male should be around 4-5 inches. I also have a male salvini at about 5 inches , who is a terror by the way, in the tank by himself right now. My plan was to switch all the terrain around, add some dithers and the grammodes at the same time. Can anyone recommend some nice active dithers for this setup. Advice is appreciated.
