gravel is for my Red devil haha he loves the gravel if i took it away i think he would commit suicide or something all he does it put gravel in the mouth and build piles of mini mountains in the tank like the one you seen in my tank haha
Ohh.. gravel's fine.. I was just talking about gravel color... heh.. but that's only my opinion.. I'm not too much a fan of blue.. have it in my 20 gal.. and wish I never bought it.
