Mysterious white blob

[SLCarrillo]

I have no idea what this is but it wasn't there yesterday. It looks like a giant egg sack but I only have 5 turbo snails and 10 hermit crabs in here, all accounted for.

I will try to add a better picture it's in the back of my tank. I tried adding a video but it won't load.

It looks like a melted mushroom or anemone. Are you missing any? Did any come in on your rock?

Do you have a wrasse?

 

[SLCarrillo]

I have no fish of any kind or any anemonies or coral. I had some tiny aiptasia a few months back which I killed with aiptasia x and haven't seen any more.
I am now wondering if it could be related to the algae tablets I gave my hermits last night though I watched them all get eaten?

Looks like a cat to me all jokes aside are we discussing the thing at the bottom of the rock? Maybe a better pic?

Well I tried to take a better picture for you but I think it may not be an issue now. It's gone and a bunch of crabs are there. I guess they ate it.

And yep.thats a cat. He's decided that it's his tank (even though I pay for it and do all the work) and nothing happens in it without his supervision
