so i was cleaning my tank today (freshwater planted), and i noticed these tiny red worm lookin things in the sand... they were threadlike, i tried getting a picture, but the focus isnt the best. any idea what they are?

Could be nematodes They typically are introduced with feeder fish what have you got in the tank?
im only feeding flakes, so it shouldnt be that...

but for fish in the tank i have:
1 x common pleco
1 x red-tailed black shark
1 x betta splendens
3 x black khuli loaches
4 x red rasboras

2 ghost shrimp
a bunch of MTSs

for plants:
a whole bunch of anachris
a few cabomba
a few water wisteria
a water sprite
two ruffle swords
a melon sword
 
They appear to be tubifex worms, they sometimes come in with plants, a cory or even a coolie loach should root them right out. They are harmless.
