sublunary Posted February 25, 2021 Share Posted February 25, 2021 Looks like colonial tunicates of some kind. They are filter feeders, and most fade away pretty early on. If they stay for you, that's pretty cool. 3 Quote Link to comment
Tired Posted February 26, 2021 Share Posted February 26, 2021 Agreed, looks a lot like tunicates. Could possibly be a sponge? Either way, harmless. 1 Quote Link to comment
