Hitchhiker on live ocean rock

[tylo92]

Hey all. I originally thought this was a sea squirt but then I was told that they are smooth. Responds to touch and has one hole at the end and one at the top. Want to try to see if I can keep it living. Thanks.

Red condominium tunicate (at least, that's what I remember it being called). They're filter feeders, but otherwise pretty hardy. A bit of particulate food in the water on a regular basis will be required, though the exact frequency and quantity of them may be harder to pin down. I would have at least a couple days a week where the water is made cloudy and takes >20 mins to fully clear.

Something like Polycarpa circumarata or this https://www.seascapestudio.net/reference/invertebrate.php?id=100

Thanks for the answer. I appreciate it!

Surprisingly, one of my local fish stores had a tank full of this live rock from the Gulf. It's been so interesting to see all the different life on the rocks. I am still figuring out most of it and trying to keep it alive.
