Maybe this seems like a strange post, but I did see him poop! So wild. Out of this tiny, tiny hole comes a series of pink (could have been the blue lighting, but looked pink LOL), small little pellets. At first the fish went for them, thinking it was food, but left them alone. I do have lots of coraline algae he must be eating, so pink seems like a reasonable color:roll: So TINY!!! Incredible life in my SW tank.
