I like some aspects of sand such as it gives the rays something to do since they are always searching for food, even after they ate. It gives them a place to hide even if you don’t have any decorations in the tank. I also feel as if fish tend to act more secure, natural when there is a substrate bottom rather than living on a giant mirror.Hey my freind, can I ask how your rays do with sand in the tank? Do you reccommend doing this or advise against it? Both breeders I have purchased rays from use bare bottom tanks but i think the sand looks more natural. Just curious as to your thoughts and experience? What sane do you use?
the downsides are that you need to go sifting through the sand every 6 months when the rays loose their barbs. I try to pull them out of the tank as soon as I realize they are gone, but I can’t always find them right away which can be un nerving at the best of times. I don’t typically have much issues with pockets of waste in the sand as some people suggest is a thing because the rays are always stirring it up. So in my opinion the good typically outweighs the bad. As long as I can collect them before incident.
I have used blasting sand and pool filter sand and I think blasting is my favourite because it is a better price point and also it is a bigger grain size. If you have pups on too small of a grain size, sometimes they have troubles with separating food from sand and they stop eating, in which case you need to pull them out of the sand to get them eating again.
