hi all .
it has been a while .
i hava a 60 cm mangrove jack and he is just starting to show signs of swim bladder problem .
cant feed a jack peas .
anyone know what i could use on him?

A good diet, try daphnia that helps digest the food.

whats the nitrate level? sometimes if its high that will throw a fish off balance. has he added anything new a week or so before the symptoms started?
