Growing on live rock I bought. Wondering if the anemone is one I need to worry about. Are the red ones corals? Wondering about the light green and the dark green. The dark green piece just came out and has something growing on the top.

The macro algae is mermaids fan. The anemone looks like a very interesting little rock anemone. They typically don't have bubble tips, but I imagine it's just puffy due to new water chemistry and lighting. The red stuff isnsea sponge. I see nothing to worry about. Looks like a typical piece of uncured Florida live rock.

These are aptasia anemones and can reproduce very aggressively. While unsightly and as all anemones are able to sting other corals and fish, there are many methods to control them safely.
