    I got these growing in the shade.

    Rather big, about 80mm. The hole is about 5mm. Black with a velvet feeling.

    Are they Tunicates? Or Sponges?

    Most sponges will die if exposed to the air for more than a minute or so. But remember that die - off will then happen in your tank. So probably an easier way would be to take a scalpel or razor blade and try and cut off as much as you can outside the tank in a bucket with some tank water of which you can throw away after this has been done. Remember to wear gloves to protect yourself from any potential harmfull bacteria ect.

    Definitely a sponge. Tunicates are more individual like pineapple shaped animals. If it starts growing over into the light then it's a photosynthetic sponge which is bad as they can grow extremely rapidly and overtake your tank.

    cool
    They are not overlay aggressive as in taking over the rocks. Just found them to be another interesting part of this hobby.
