I think i have room for a few more fish but I am not sure what to get. I have a 20l with currently one Adult platy, five adolescent platy, a Dwarf Gourami, three assassin snails (which may be removed as they are no longer useful), five amano shrimp, plats (java moss, fern swords, annubias, ludwigia). Run of the mill. The temp is 78 the water is at 8.2ph. I almost bought some guppy's today but I was thinking that was boring. The problem is that with such a small aquarium there are so many interesting fish that I can't get, but I am not sure what I can.
