Hey guys I’m wondering about a possible problem I may be having with my teacup stingray. She doesn’t like to bury herself under the sand. There isn’t any noticeable spots of fungus that I can see. But on her tail/bone there is a ‘fuzz’ like appearance. The ‘fuzz’ is very fine and only seen directly under light. Her belly is a little pink but it’s always been that way. If it’s not a fungal problem could it be that my sand isn’t fine enough for her? She seems perfectly healthy otherwise; her diet is very well balanced and she’s always ready to eat; The pH level and ammonia level are also fine as well. So if anybody has any ideas or suggestions I would love to hear them, thank you!
