Salt-water chameleons

Maybe it's because they're transparent. Maybe it depends on what they're eating this week. Maybe it's where they've settled. Maybe they're akin to mood rings: whatever the reason, the orange-striped green anemones, Haliplanella lineata, in my tank are never the same colour twice in a row.

This is the largest of these tiny anemones, parked for the moment on sea lettuce in a bed of deep red Turkish towel and red leafy algae.

Open, showing mouth lining. Pinkish today.

Almost closed. Just the slightest hint of orange. And the green base is blue.

I don't know what those white lines inside the closed anemone are. Ingrown tentacles, maybe?

Tomorrow I'll be travelling, and won't be posting. See you Sunday!
