Any chance of a clear picture?
It could be a snail or a piece of bubble algae.
Does it look like a little hard green sack of water? ..if so it is a piece of bubble algae
Sorry took a quick iphone pic before i ran out. The sac was brownish with dark brown stripes near the pinched end. The sac itself was hard but appeared to be hollow and empty. it was about 1'' or so big.
kidney bean eh?
Did you keep it out of the tank?
Does it smell? (careful..if it is a dead snail - it will near knock you over if you take a good wiff...)
We'd still love to get a better/closer pic of it so we can figure this out
