I read on another message board that when they die, they pollute the water and are toxic for the other fish. I also read, that they don't live that long. The message board I read was against it.
I was tempted to buy one myself when I first heard about it. But, if I am not hear, and it dies, I wouldn't want it to affect my other fish.
Again, this is what I read so I don't know how true it is.
How do you feed it anyway?
