if there is a lot of debris you are overfeeding and maybe feeding the wrong food.
find higher protein food with less "filler" like corn or wheat. feed MUCH MUCH less
and the fish will grow. if you are seeing their poop, it is diagnostic of over
feeding or problems. see diagnosis by poop here.

what you need is better filter too. get rid of the gravel BTW and the tank will stay
cleaner. Ingrid

My 6 goldfish poop a lot in their 42 gallon hex tank, I was searching
for a tank mate that might eat their debris.

Will snails do the job? Or are there any other creatures better suited
to this?

I don't have live plants in my tank, and don't want to fuss with them.
