anybody ever have their emperor or kerri tetras spawn? I have ONE fry in my tank and don't know who the parents are. Can't tell if it's the emperors or the kerri blues. I know it's not a ram or an oto, the only other inhabitants. It's about a half inch, elongated, and has a bright gold lateral line, which neither tetra does....I can't believe it has survived to "bigger than a gulp size", as there are loads of fish.
