An anemone and a sponge?

If you can, tell me how I should encourage them to grow. Thanks!

The first pic looks to be a majano pest anemone. The 2nd is a pineapple sponge harmless filter feeder.

I would hold off on the mojano anemone assumption. Let it grow out some undisturbed and see what it looks like then. Almost looks like it may be a bubble tip. Sponges are good to have .

I think it's a Majano, as well. Majano's can get that bulb-tipped look too. They can be very beautiful, the problem is they spread like wildfire, and can sting anything around them.

+1 to Majano.
