Was cleaning off algae from a rock and found these....

[jadenbroc]

There are 2 things I need help on.
1)My sump and tank walls are getting a ton of those little white, hard specs.
2)Was cleaning some turf algae off some rocks and noticed these things on the bottom.

Am I in trouble?

Pineapple sponges. Cool little filter feeders and Spirorbid worms. Also filter feeders.

 

[AllSignsPointToFish]

Nope. They are both beneficial.

The larger white specks are pineapple sponges.

The smaller white specks are spirorbis snails.

All filter feeders. I have them all in my tank.

I love how randomly reading other people's posts answers my own questions before I ask them. I saw a couple of these the other day and thought about asking what they were but couldn't get a good pic.

Are these spirorbids? Over the last month, I have gotten them in the fuge section of my sump and saw 1 the display. I have Only ever seen them on glass

Those look like limpets(at least they look like they have a hard shell) good CUC, eats algae and coralline.

+1 to limpets

They DEFINITELY have a hard shell.

+1 to limpets

Never seen them on any rocks just on the glass in the sump and 1 on the DT glass.
