Oh man EB's are a pain in the ass... Their digestive system sucks and they can't handle protein... Greens for sure and they're small and grow really slow but I wouldn't feed them a lot... Mines almost 2 years old just got recovered from parasites, I feed him only every 3 days spirulina brine and cichlid excel... You should get rid of everything but a pair that forms then add 4-5 clown loaches and delhezi or some other poly... Tank looks sweet tho
