Very lovely. I thought Blue Eye Cardinal and the damsels were fighting, but it looks like they will seek him out and he will seek them. They seem to play in a way the damsels never did with each other. He stays closer to the bottom and doesn't come up to compete for food. I didn't think he was eating but then I realized my cheto was all but gone. Hungry as a herbivore.
