I'm thinking they aren't considering they need 24/7 lighting and I had them one time, they got to about half an inch and someone turned the light off for the night. xD Yes they were all dead. No where on earth has 24/7 lighting so I don't think they are natural creatures...Does anyone know?

They are found worldwide in freshwater, brackish water or saline pools, as well as in shallow lakes, peat bogs and moorland.[2]
