firstly Merry Christmas to everyone on the forum. Hope you all have a splendid day.

So my 350L tank has finished cycling and just doing a water change when I’ve noticed lots of tiny life forms in the tank.

Little white bug things round body thinning to a point with a tail, these are very very tiny and can’t get a photo, they are crawling on the glass.

the second one was a brownish clear worm, almost like fish poop but wriggling.
 
May be some type of detritus worms, feeding on fish food in the gravel. They are harmless and many fish eat them. I would do a water change and a good vacuuming of the gravel. Reduce the amount of food you add to the tank.

I agree with Retired Viking. If you’ve been using fish food there’s probably an accumulation that needs to be syphoned out. Cut down on food.

I did a 75% water change and gravel vac before adding fish to the tank.
I’ve not been adding food to this tank at all as I was using ammonia to dose the tank.

I’ve added plants during the cycle so possibly come in off a plant ?

the little white things I’ve identified as copepods and apparently so I’ve read it’s a sign of good water quality and doesn’t harm the fish in 95% of cases but can cause distress to fry.

so the worm thing was just some live food them, an unexpected Christmas dinner for one lucky fish is it didn’t get vacuumed out.

The best I could get of the worms
 
Happy day...that's a great background. Those little wormy fellas will make for a nice snack. Carry on.
