sac like things under my mushroom

[nozzano22]

There are sac like things under one of my mushrooms. They seem to enlarge themselves and then I was able to see that there is a white thing in each sac, and after a bit they 'shrink' back down again. When they are enlarged they kind of fold the mushroom in half, and then when they shrink again the mushroom goes back to looking normal.

Does anyone know what this could be?

Thanks.

Can you post any pics? That is hard to say without seeing it.

You most likely have something common in your aquarium, and the description is just what is delaying the identification.

Bust out your inner Shakespeare and give us a good description or snap a picture. :)
