Christopher Marks Posted March 16, 2019 Share Posted March 16, 2019 @Belikin most likely it's a cryptic sponge, a common hitchhiker even on cured rock. They're friendly filter feeders. Quote Link to comment

The easiest way to figure out if it is a tunicate, especially if it isn't transparent, is to look for a second hole. They have an intake siphon and an outlet that their ass is connected to.

Yep, I was able to get a better look today, and found the outlet. Wonder if it will stay alive for long in a tank? Quote Link to comment

Unfortunately, probably not if you have a newer tank - most of the ones that do well in our tanks are of the colonial type and typically only in older, established tanks. The singular and larger tunicates generally don't do well - there just isn't enough for them to eat in a new tank. They are filter feeders. I've got a few (I think - colonial tunicates and sponges can be hard to differentiate) in my tank, but they are small and of the colonial type: Quote Link to comment
