About 1 month ago my green terror just stopped eating. It will sometime put the food in its mouth then spit it out. However he is still the same aggressive fish and his colors are still bright and colorful. It’s been a while so I’m sure he must eat a tiny bit of food but he is not like himself. I have had him for 4 years and I don’t know what to do please help.
Sorry for the poor quality but this has been unusually large for a while now and I’m unsure if this has anything to do with it. He is in a 125 with a festae cichlid and has been for the last 3 years
