I have read everywhere to feed your RES every second day, approx a head's worth of pellets. Is that too little? My 2 RES's act like they are starving all the time - begging, splashing, and basically going nuts every time I stand up in the living room. I know they will beg for food, but is it possible I'm not feeding them enough? I'm also giving them occasional veggies or protein, so I know they aren't starving, but they sure act like it!
thanks!
