starfish

red starfishI have two starfish in my marine tank. They do a great job of cleaning up. The sand sifter (Astropecten polycanthus) is the pale one and is usually hidden under the sand. The bright red one (Fromia milleporella) crawls all over the rock and glass.

snail babies

snail babies
I believe these are Astrea snail babies hanging out with Mom (or Dad?). A few weeks ago, I noticed many (50-100?) on two of my large snails. These elongated little snails are gradually growing larger. There are still several on the big snails, but now I'm finding them in others places in the tank and in the refugium. This is good news. I could use more snails and would rather get them for free.

This is some nice red thing growing in my tank. Colorful and interesting. I'll have to ask JD what it is. Maybe a sponge? I see a small aptasia in the middle of it and a big one on the side. I'm going through a lot of Joe's Juice on these guys, but gradually am finding fewer on them in the tank.

Note added Nov 7: JD says this is a red coralline algae. A nice thing to have in the tank. Here's some info from the Monterey Bay Aquarium on coralline algae.
