Bi-Valve ?

I have seen these clear, globe - like critter with two small pipes that pulse from time to time. This is a local critter that came in on the last WC. It’s a very simple looking critter, prehistoric?

Hi Mate, are you able to get different photo, make it a bit clear or/and different angle ?
It look like a jellyfish SP.

If they pulse, its most likely a tunicate of some type

Sea squirt

Thanks, that was my other guess, very invasive. My traps get covered within weeks.
Here’s another critter I’ve never found a name for, it’s inside the orange sponge on left. There dark brown, and open with 4 hard petals, and when closing they snap close very loud.

Boy, you've got me on that one @KJ ever hear of such a creature?

Tunicate or Sea Squirt are reef safe, only some of them if they are disturbed too much can squirt with them water and really small amount of sulfur acid (which can't do anything bad in to your system. You are lucky one, just they are rear, and they can't survive for too long in the DT.

All I can see is dark spots on top of the sponge

Sea squirts - you can try to feed them but I hear most are a nightmare to try and keep alive

Thanks for your reply, but this system has been running for over 2 yrs, and the Sea Squirt has been there for a few months. I use water from the bay. No filters, just pour it in. I also just restocked this tank with fish, and yes it’s over stocked, over 40 fish, crabs, and snails in a 60 gal.

Sorry for the bad pic. I haven’t seen one since, but it was very interesting while it lasted, then someone ate it
