Don't need sand but it's natural for them to hide beneath the sand bed. I would think sand provides an added sense of security. And what about the digestive benefits of sand? Is there any?
my rays do better i feel with sand. and seem to b more happier. also they sift thru it to find earthworms n stuff. also the geo's like it so i use sand once they rays are on there own i will go to glass bottom big fan of bare bottoms
Nope don't NEED. But will they be happier with...I think so.
Bare tanks are fine, but I believe that there is a certain amount of natural dermal sloughing that sand or round smooth gravel provides/enhances that glass can't.
