Thank you very much... But the fish disappear because it is in the game code or because it is a bug?

I am sorry for not giving the necessary information. Well, here I have it:
OS: Windows 11 (64x)
Graphics: Nvidia Geforce GTX
I spawn the fish with an egg, in creative mode ( I used commands like /time set day).

Thank you very much, I tried it and it worked.

Thanks!
