PNT shell flacking.

Hi guys,

I've been struggling with this problem for a while but could never solve it.

The shell is generally flacking or peeling off. Like many this layers bit by bit peeling off. The pnts have been problematic for a while. Previously was worse can see the shell got whit parts nd at times fungus. Tried those rainbow anti fungus and yellow powder.

Works a bit and at best the shell no more fungus. But will still peel.

My 2 PNT the shell alone is 7 inch long. One appetitte good the other poor.

Is it their diet? I feed pellats.

I see othe pnts their shell smooth ang glossy. How to fix this problem? Thanks guys.

Btw, kept for 7 yrs already.

Rgds,
