I'm planning a green terror colony 180 gallon tank. I want to add some dithers to add life to this tank. Will goodeids be good. I'm thinking of A. Splendens or I. Furcidens.
so would furcidens be the better option?
CIchlids will most likely eat all the babies, unless you have very intricate hiding spots that the GT's can't get into.
Pike livebearers would probably work. I have kept them in the past, and the females get quite large.
Personally I might go for Buenos aires tetras instead of livebearers. Should be too fast and large to eat, also they are from SA so will keep the tank geographically accurate. Or, a few striped silver dollars would work fine in a 180.
