I only just bought him two weeks ago and he was doing fine eating the and everything right up until yesterday i put a new plant in that floated on top of the water and this morning i go down to feed him and he is wedged inside it and dead... I'm guessing he got caught in it and couldn't get out.. I don't know what else it could be. His water was near perfect i fed him twice a day and he was acting fine right up until this.. I'm bummed.
