So I got a great deal on an algae blenny about a month ago. When he showed up in the mail he was about double the size I expected and he got right to work. This fish never stops eating. The only problem is he never stops pooping… he goes into one corner of my tank and drops these dark green half inch long turds all day! Like , 10+ turds in a 24 hour period. Is there anything I can add CUC wise specific to this?
