I have a very urgent issue. Im a lover of lionfish, especially volitans...! I have small-medium sized lion in a tank with 2 zebra morays and an undulate trigger..they have been with one another for at least two months and all get along well. my volitan "WAS" a very aggressive eater, chasing down any live food that it saw. But as of two days ago he has paid no attention to any food, all attempts have failed, and just sits at the bottom of the tank motionless. Is he dying? My ammonia is not exactly at 0, and will be doing a water change on my day off (48 hours) but i dont think this is a contributing factor as my trigger and eels are at 110%. can anyone help as i dont want to lose this beautiful fish!! any help will do..!
