Unknown critters in my sump - Help ID Please
 

Hi, Dave here. I'm very new to the hobby. I started a 72g in November. Built a 110g sump in my basement and plumbed it in over Christmas. Anyway, I am very much on the learning curve and today was no different.

I hadn't looked at my sump in a while as I've been outta town and I found it covered with these interesting little critters. I don't know what they are, I don't know if their bad, and I don't know what to do, if anything. Nothing has shown up in my display tank but my sump is covered.

I have 2 different Nitrite test and both have said 0 since day 1.
Ammonia 0
ph 8.3 ish
salinity 1.023

Live stock:
FISH - Yellow Tang, Tassled Filefish, Foxface, Mairne Beta, 2 clowns, 2 yellow tail damsels, 3 chromos, a shrimp I've only seen 3 times, and 1 small unknown thing.

CORAL - I have 3 soft corals that look nice although I have no idea what they are. (I know, I know, research what goes in, but ignorance is bliss).

Anyway here are the pics.. Any info would be appreciated. Thanks.

I just looked at the posted pictures and they are very small. I've also posted them on my photo site were it's easy to zoom in.

its a litte rough looking at the pictures but i think they are sponges and they are very good to grow in your sump. the are filter feeders

Look like Spirorbid Worms. Harmless filter feeders. According to Melev's ID site, anyway :smile:

Agreed,
I see Spirorbid worms and pinapple sponges.

ditto :biggrin:
