What is happening to my toadstool?

[bluedevils38]

So I noticed this the other day on my mushroom that is about a foot in diameter and it has gotten a little bigger! Can anyone te me what's happening and if I should be concerned! Thanks in advanced

I have a green one and when it started splitting it kind of looked like that. A zoa frag fell on mine and caused it.

So did it go back to normal and if so how long did it take

 

[miyags]

Could be your queen angel be eating it?

 

[bluedevils38]

I haven't seen him nipping at it!

If it starts to spread you could always cut that section off with a pair of scissors and it will soon grow back.

Alright!
