Got a French angel from one of the LFS recently and QT him in a pail with air pump and WC 100% fresh water every day for almost 2 week now. On the 3rd day he develop lymphocytic, he eat well on and off , when he is happy he can eat more than 10 big pellets on one feeding. When he is stress, he will not take anything for the whole day.
The cotton wool on its tail grow smaller and his body all clear but this time new and more developed on his top fin and one of his gill fin. Had done an anti-bacterial bath on the 7th day to reduce secondary infection.
Now do you think I should cage him in the display tank or let it go into the display tank? Or should I just QT him till he recover? I know it could take weeks to months.
Condition of the fish: still fat and eating ok, no scratching, still swim around the pail and no sign of itch or velvet but I also worry the pail is too small for long term QT that causes more stress to the fish.
Any experience reefer/ fish expert to share?
