How treat of him ?

That has to be lymphocystis, like Silverfang said. It doesn't look anything like Ick to me. My Betta named Epilepsy just passed away due to lymphocystis (or that was atleast part of the cause).

Just make sure to keep the Bettas water clean. There really isn't much else to do for him.

Ich is not a fungus. It's a parasite.
