I have been searching for some alternative food options for our little guy Rock N Roll who seems to have some trouble digesting the Hikari Bio Gold pellets that our other betta eats. I picked up something called Hikari Tropical Micro Pellets thinking that maybe because he is very tiny those might work better for him. But before feeding them to him I want to make sure that this type of food is ok for bettas? They are not specifically listed on the package - it says "tetras, barbs & small fish" If it is ok to feed him, does anyone know how many micro pellets would be equivalent to one Bio Gold pellet-sized feeding? TIA!
