mine is about $20.00 but I think it's more stable and worth the price! It's a two way feeding apparatus and the little loop you see near the pincers , is for you to dangle it with a nylon thread from the center of the tank. I really like it , as the grip is pretty firm. I'd like to know if any of you have seen this in the stores? it comes with some square pieces of vitamin packed leaves. Really yummy , I felt like eating one!
