What could be the problem?

Oga your fish don die 😂

You might be raising a shark in there, dive in and see for yourself

Have you ever listened to this?

Bro to bro stop giving them feed kindly reduce the water to know if fishes are still in there 👌

Bro reduce water na, clean the surface, no be like your room na, clean the pond Eje

2 months now and your mind no tell you say them fit don die

They have adapted to the sinking feed you're giving them. Try a floating feed and you will see them come up.

U cover with lower Net how u wan see them?

When fish are bigger than their expected month they don't come up only the smaller size do and besides that's not a floating feed you're giving them, so why should they come up when the food goes down?

Reduce the water in that pond. You will easily see the fishes and their sizes

@grok what will cause that?
