Amphipods????

Are these amphipods growing in my tank? The just stick to the side of the glass and return piping in my overflows. I never see them moving, but they multiply like crazy.


I know.....the picture sucks.

Thanks
Jack

 

Those are pineapple sponges.

Amphipods are arthropods, hard external skeleton that they must shed to grow.

How do you get rid of them?

 

You don't they eventually die off as the system ages.

They are usually found in dark/shaded areas, sump, behind pumps heaters......

Harmless filter feeder.

 

Don't worry about them...they will more than likely disappear if not its just sponges....I have had huge colonies before

 

I had thousands in my sump and overflows and cleaned them all out......so I thought. Back they came......

 

Only because the conditions are right.

They are filter feeders, so in tanks with higher levels of suspended particles or DOC they thrive.
