Unresolved Who stole the cookies from the cookie jar ?

So I peek into the tank in my hallway and what do I see ? ..someones been eating my awesome neon green sponge !! This is a who done it mile a minute thriller that needs your help if it's going to be solved !!

The suspects are as follows :
*a less than brilliant Molly with a heart of gold
*a picaso trigger with an insatiable hunger for vast quanitys of mysis and fish tails
*a sly sixline wrasse that hides in the shadows
*a damselfish with a bad attitude and a lot to prove

Now who done it .....

 

My best guess is the trigger, the other may occasionally peck at it, but IME will not eat it.

 

I had a brittle star eat one of my sponges!

 

I'm gonna say the trigger as well but probably pickin off goodies and spittin out the sponge.

 

trigger

 

Ah yea I bet he is eating stuff off it and spitting out the sponge
Thanks guys

 

Clever way to put it....made me laugh.
