I am wondering if these would be okay in a 55 gallon community set up? Planted, with angels, ottos, and live beares for not. Maybe a school of glow light tetras.
Adult Aplochelius Lineatus (Gold) can grow quite large(3-4 ins) compared to the other fish you have mentioned. How big are your Ottos? They should be OK whilst they are still young but keep an eye on things as they grow.
the ottos are about two an inch big now. I do have small guppies and platties, so i will wait to get the killies for now until I can move them into another tank.
