So i need to know whether or not i should keep my mantis w/ a stingray. My tank is about 30 gallons. I have 2-3 inches of sand w/ a small amount of LR, mainly some big pieces(helps provide more space for the stingray). Anyways should i remove the stingray? Im not sure what effects the stingray may have on my mantis and i don't want to keep the stingray if it is bad for my mantis. Please let me know what you think. Thanks
Jonathan
