I have a 20L with 3 Cajun dwarf crayfish (about 1" each), 4 red cherry shrimp, 1 ghost shrimp, and 2 nerite snails. All have gotten along great! I'm considering adding some celestial pearl danios, Endler's livebearers, and oto catfish. I know the Endler's and otos are shrimp-safe, but I'm not sure if the crayfish will be too agressive for fish. anyone ever tried these or similar species together? let me know if you have any advice!
