Green Hairy Mushroom Splitting?

Topping off with fresh water today and spotted this:

It looks like two mushrooms but in between there are pink strands still connecting them.
Is this normal or should I be concerned?

The pinks strands are called messenterial filaments and are part of it's "stomach." It looks like this individual is splitting, and in the later stages of it at that.

Cool! I checked this morning when they weren't spread out and that mushroom had split into three portions instead of the two. Found another 3 more of my original 6 splitting as well. Crazy how fast they grow!

That's awesome!
