i would say it is definitely skinny. the bad thing is i traded my tank that night. i brought it to his house and then i got to see the stingray for the first time there and i didnt know very much, but figured i could get it eating, so i took it. now i am finding that this will be a bit more challenging than originally thought. i am going to try and stick with it though. will the ghost shrimp be a good bet if i cant find the black worms? i am supposed to be getting some live red worms for him too, hopefully it will start eating something.
