White worm spotted!!

[Cmlee]

I have never feed tubix worms but today I saw a string of white colour worm swim in the tank. Is it the beginning of bateria invasion?

It is common and usually it is due to overfeeding

Yeah, those are just nematodes or detritus worms, they exist in all tanks and are harmless.

Usually if you can see them climbing the tank glass or swimming in the water column, means that their population is higher due to lots of food availability (ie. waste and excess food), so they reproduce quickly. When there is less food sources, their population will also naturally decrease.

Small fishes will eat them and they are very good food for fry too, can consider them as free live food for the fishes.
