I could agree that bubbles or maybe even more rays might make a big difference in the enrichment of a rays life. My guy doesn't have a girl yet so he gets sand

I know it seems silly to think of a fish being bored but I think he would be bored without his sand![]()
Your argument doesn't really work man, They don't live in huge glass boxes in the wild either. Do they?waynes world;4588593; said:i have never seen a sea bed or river bed with a glass botom.
It may sound silly for a person who dont know these animals, but of course they need a stimulating environment -other than just the food who fall at their heads. Same goes for all animals. Of course the rays can survive and reproduce in pure BB tanks, and trive (to some degree), but so can humans living in a prison cell, cows living in a barn, birds in "clean cages" etc... still it`s not neccesarily optimal. The way i see it, it`s really a question about what each and everyone focus on in fishkeeping...; Best possible environments for the fish - or as simple as possible for the keeper.I know it seems silly to think of a fish being bored but I think he would be bored without his sand
