I got a King Male, Sumo, a couple of days ago because my fav betta Sunkist passed away suddenly (on my birthday

). I was wondering how much I should be feeding him. I feed all of my other bettas 4 pellets a day (2 in the morning and 2 at night). I feed all my bettas Hikari pellets. I vary it with some higher quality food also but am trying to get rid of it. Do you think it is ok to double that? So 8 pellets a day?? This King Male is MASSIVE! He is probably 4 inches and 3/4 an inch thick. HUGE! I just feel like I am starving him if I feed him what I feed all of my others.
