Hey all so I received two salvinis from a buddy when I took over his tank. However I would like to move them to a 90 they are not paired up as I thought. The Female is larger compared to the male. In a 90 would two non paired salvinis work with say some lemon tetras. Or should I add 1 or two more cichlids to the 90 with the Sals I was thinking a group of Firemouths.
