Please keep in mind that as these little guys die, they give off a poison that is no good for your tank.

If you choose to get rid of them via a chemical means, like flatworm exit for example, siphon as many out as you can then be ready to siphon them as they die.

If you could find a blue velvet, that would be the best option but I rarely see them in stores so best of luck.
