Hey I was wondering what I fish I should add to compliment the fish in there presently? Some of the fish that I am looking at are green neon tetras, cardinal tetras, Trigonostigma hengeli, or something else. what do you all think? I was thinking green neons becasue I have seen how they look when acclimated but they do not always look very bright. I plan to add a school of 10 or so. Give me your advice please.
