I bought a beautiful pair of S. elegans and I knew that they were vegetarians and that their diet consisted of algae, so I let algae grow in their tank for months, tons of it, even blue-green algae, which they like. The tank was very well established. They went through the algae in roughly three weeks, then they stopped eating altogether. I bought algae tabs i transferred algae from other tanks and nothing. The female died yesterday:cry: and I frantically moved the now alone male to a tank with more algae. I don't know what Ill do after that. Long story short I just don't see this species doing well in an aquarium setting, they're just to demanding, at least for me! At least I can say that I tried.
