I have a 40l tank with a substrate of gravel over a layer of plant nutrient compost. Yesterday my wife noticed a worm thing up against the glass under the gravel, about 3/4 inch under the surface. I tried to extract it with tweezers but it squirmed away and hid and I lost it. Today we saw it again and managed to catch it and take it out, in fact there appeared to be two worms caught (unless it was one that got cut in half by the tweezers and the separate bits were still moving.
It looks exactly like a small earthworm about 2 1/2 inches long, kind of greyish pink in colour. I assume it can't be a normal earthworm as they drown under water, don't they? I am concerned there may be many of these living under the gravel and I hope they are not harmful. I do have live plants so I assume it may have come in as an egg or a tiny worm on one of those.
Does anyone know what it might be?
