Depends what you want - some people like rainbows, i like kubotai rasbora and galaxy rasbora, some people like lemon tetra others like black phantom tetra some like rummynose rasbora other like rummynose tetra. There is no right answer. Personally i like dwarf cichlid and would get a pair of nannacara or borelli apisto but that is me.
you could try two blue or gold rams, maybe an angelfish either. along with this i also recommend cardinal tetras over neons, being much hardier and also bigger (angelfish can sometimes eat neons)Can cichlids be kept with neons and juliis? If so that would be awesome
The less aggressive ones - the more aggressive ones might be upset with the juliis ignoring their territory. Btw I said dwarf cichlid - larger ones will snack on the neons.
Okay cool. Ive researched and people are saying dwarf cichlids are expert level fish to keep. Is that true?
