Dear All,

From my recent observation, i found my tvr sometime float & its back is expose at water surface. This happen started day 4 after WC. It seem not like swim bladder problem as the fish can easily siwm to bottom. I also observed some poo float at water surface and can found small air bulble.

My 1st guess maybe due to too much pellet feeding. Then i reduce pellet feeding from 3 time to 2 times.

However, i still found some poo with air bulble and less fish floating or reduce frequency of floating.

Another theory said this situation cause my bad bateria at water surface. At our warm/hot environment, the water surface tend to have bad bateria. This bad bateria will cause digestion problem to the fish and generate air and result fish tend to float.

Solution is implement overflow to the tub, add some water and let the surface water overflow out of the tub. In addition, feed fish with spirulina food.

Guy, any comment ?
