I'm not sure what specie it is since it came with the tank when I got it a long time ago. It have survived a long time and I hate to lose it even though it's nothing fancy. The stuff that's coming out is like white and filmy. It looks like smoke when it is release.
It hasn't deflated completely I don't think. Like I said before, I have seen it shrink down when it got too much flow. The water it's in now is all mirky so I'll need to replace the water and then try to take a picture. I can see the mouth open pretty big so that doesn't look good.
I'll try to upload a picture but I always had a hard time getting pictures here.
