Would be in a standard 40 gallon, have a DG a black molly and flat head minnow (odd bunch i know) I used them too cycle my wolf tank before he arrived and I didn't have the heart to let the wolf sort them out so I moved them to a 20 gallon storage tub with a heater and a aqueon 30 gallon filter. Now I kind of want a bit more of a community tank and I was wondering what dwarf/small cichlids that would be compatible with my current lineup.
