Love this thread--and this species! My little one may be too young to sex, but here goes nothing. It's about 1.5" - 2" in length. Bought a month ago. What do y'all think? I'm enjoying him/her so much that I'd like to get a couple more, maybe even try to breed them. How many unsexed specimens could be safely and harmoniously stocked in a heavily planted 75 gallon or 90 gallon (either alone or with a group of Congo tetras and a single syndontis)? I'm less worried about maintenance issues than I am behavioral. They'd be from the same batch as this one and are all wild caught. Thanks!
