Flatworm Predators

[Jeremy K.A.]

Hey everyone, I have a 5 gallon reef setup and have some small brown flatworms. I don't have a ton so I'm looking for something, preferably an invert, that can live comfortably in the tank and help control or eradicate the flatworms. Any suggestions?

In 5 gallons nope, maybe hermits. Siphon them out, do not feed the tank and try a blackout.

I do flatworm x every time I see a few of them but you have many that you dont know about the toxins can nuke your tank.

Buy 1 package of flatworm exit and mix up 10 gallons of saltwater - with similar parameters to your nano reef.

Overdose the flatworm exit, change 90-100% of the water dose the flatworm exit again and change 90-100% of the water. If you do this twice over 2 weeks or so I can almost garuntee it will eliminate the flatworms and you won't have to a) look for a flatworm eating nudi b) condemn it to starvation just a few weeks later. Besides the fact it will quickly starve to death you have to be real lucky to use a predator that only eats one thing and have it actually find and eat every single one before it starves to death.
