thats a good question. I dont have an answer for you but from my observation i'd say no. my 87g bci poops about every 6-7 days and eats again. my sub adult bci's only poop about every 14 days or so. and my dumerils seem to pee every day but only poop about once a month lol. I honestly have no clue but thats what happens here at my zoo.
