Photo: Unknown object in axolotls tank(in the tree)

[Courtney22]

Can anyone help me with something? I have 3 axolotls, all came from a no-substrate tank and mine has a sand substrate. I have had them for several months however me and my partner discovered this in the tree in the tank. We don't know what it is. Can someone help? They are about 1cm maybe smaller but we have not touched then as we are unsure as to what they are

Just to clearify, the tree is the green object in the tank yes? If so are you 100% sure that the axies where in a nonsubstrate tank? Because that looks like the gravel I keep in my fish tank. If I where you I would remove immediately before another one eats it again.

They can stay in the stomach for a while. They must have come from the previous home.
