What do you mean by small feeding every other day? At that size hopefully you will be feeding at least twice a day. Also, I would drop the Tetra pellets, most Tetra products have high starch/grain content, with ingredients such as corn starch, wheat gluten, ground rice, potato protein, dehulled soybean meal, etc ....... exactly what you do NOT want to be feeding a bloat prone species such as beani.
Good luck
