I have a 12G Nano and in the back there are 3 sections for the sump.
I was doing some maintenance today and as I pulled out a bag that has "Matrix" in it these little worm'like things were on it and I have no idea what they are....
Can someone ID these things? They are about 1/2 a CM long.....
lastly are they good or bad?
Here are 2 pics....
