Hi! So my tank has entered the ugly stage and as I impatiently wait for the right time to add intentional inhabitants, I like to spend time (along with my kids) exploring the expanding ecosystem with a magnifying glass to see what might have found its way in there. We seeded the tank with some mature live rock from the lfs and I know it's risky but I'm old school and have a love for seeing what hitchhikers might have caught a ride on the rocks. We have the usual assortment of bristle worms, tube worms and algea but I've noticed a couple I don't know offhand. One is a white/clear membrane looking thing, maybe some kind of sponge? I had a spong with a similar color many years ago but it was more tube shaped... For reference The little tube worm under it is about 1 cm long.
The other is a cluster of red bulbs or polyps on little stalks or so it seems. The red thing is about 1 cm across.
Looking forward to hearing what you all think!
