I think I have flatworms:(

[Sicklid]

10 g tank
All parameters are good!!
I havent seen damage on any corals yet!!
What should I do to remove these pest?

yeh, flatworm, but not the red kind that seem to multiply quickly. keep nutrients low and these shouldn't be a problem...may live on mushrooms, but probably not hurt them. see these a lot in fresh tanks, then they seem to go away. siphon out what ya can.

Looks like planaria flatworms. They are relatively harmless in small numbers, however they can quicky multiply until they are out of control (smothering tank inhabitants). There are a number or wrasses, damsels and mandarins that can act as natural predators. They can also be manually removed by siphoning them out of the aquarium. There are also a number of products that will eradicate these as a last resort.

Thanks, I will do a 20% water change every day to start removing those creatures!!

Any corris wrasse will go after them, the yellow corris are super hunters or the cheapo blue/blue yellow tail damsels.
Good luck.
