strange thing in my tank?????

[Chase31]

okay so i cant take pictures of it cuz of the location, might try a little later, its very very small like maybe smaller then a fingernail and it has at least (editthree little tenticals that are as long as the fingernail but very skinny there black with maybe little white dots there moving around and looks like little spikes, maybe its trying to climb the wall?

so for the terrible description will try to get a better pic after i eat lunch
