I've just done a major clean-out of my Juwel Rekord 120, removing the filter which came with the tank (it was useless) and installing a new one (which I've actually been "phasing in" for a while now).
Anyhow, shortly after having removed the old filter casing (which was siliconed to the side of the tank) and stirring up quite a bit of muck, plus giving the substrate a good stir, load of worm-like "things" appeared.
There were literally hundreds of them floating around in the water, all seemingly dead... either that, or these worms had shed, and this is what was left? They ranged from about 8mm to around 35-40mm and were almost transparent, the larger ones of which appeared to be thicker at one end, with a sort of "jagged" appearance. They're very worm-like, long and thin, definitely not planarians.
Safe to say, it's grossed me out and despite trying to syphon most of them out, there are still a few floating around. I'm worried that if I stir up the rest of the substrate, there will be loads more hidden away somewhere!
Anyone know what they are? Do they pose a risk to the fish? Where have these things been living, growing and reproducing, and considering they all appear to be dead, should I worry?
Also, are they likely to pose any risk to humans? The closest things I've found appearance-wise are nematodes and some of them sound quite nasty...
Any help or info would be much appreciated.
