It's the way they catch them. If you could get captive bread, or net caught they'll live longer. But the cyanide caught ones can eat like pigs and still waste away.
I?m trying to find a fish that?s small, feeds off of flak food and will do well with a clown fish.
I thought a citrinis would do well but I really don?t want to get a fish that?s going to die in a short period of time. I already had that experience with a yellow goby that would not eat to save its own life, literally.
