grouper 42
Member
Stars and Stripes. Had him for 9 months. One of my original fish. Never a problem. FOLRCC tank. 128gal with chiller and skimmer. No other addition or subtraction recently. No other fish ever bothered him. Found him floating face down and nearly black in color. Periodically blew himself up to ungodly proportions before I took pity on him and put him out of his misery. I had put some maricin in the tank the day before for a malady of my Lion (looks like his upper lip was disintegrating). Thinking I had killed off my biological filter and caused an ammonia spike I tested the water and the ammonia was zero. Other fish (sailfin tang, tuskfish, cherry grouper, Lion, rabbitfish) seem unaffected.
