With the neon's i will have to say NO......As this is there main diet in the wild......If i was you i would change the neon's for something else......maybe colombian's and then go and get a tbar cichlid<there nice..you have a 4ft/12/15inchs right?
with the neon's?
are these big neon's?not sure really, maybe a krib or keyhole cichld,,silver would probally eat the neon's and they need space to swim as they shoot round tanks at lightning speed
