I have two latz that i purchased as babies a year ago. They have grown fast and are now about 3" long and fat. However in the last week the one that is hosted by a RbTA has stopped showing interest in any food. Just stays in his nem, he moves around and seems energetic but doesn't eat. One this I did notice is that in anal fin and lower tail look a little frayed. I feed a mix of flake, dehydraded mysis, and pellet with two feeding per week of frozen mysis. Thanks for your help.
