I currenty have a 20g tall tank that has one male betta and eight harlequin rasboras in it. Its cycled, heated and filtered. I've been wanting to add one my type of fish to the mix, preferably a bottom dweller/s. I was thinking a blue mystery snail but then I fell in love with bristle nose pleco. Would this be Ok? Or is there something else that's similar or Would be better to get? Thanks!
