someone i used to work with at the lfs was complaining about gravel vaccing, so i told him to just take the gravel out to make it easier. with the filtration they have, they really dont need the bio from the substrate. he told me that the fish would stress out cause of there own reflection. now i myself have my tank bare, and i have seen A LOT of tanks on here that are bare. so my question is...
can fish stress out from seeing there reflection in a bare bottom tank??
