Need help identifying this

[helms20]

Sh these small strips of something are growing on my rock work and snail shells. Not sure what it is, but should I be worried?

Flatworms! Siphon out as much as you could and then use flatworm exit. Adding certain type of wrasse will help too.

 

[helms20]

Great. I'm getting a new tank tomorrow so can start clearing them after everything is setup.

 

[helms20]

Thanks for the replies.

 

[helms20]

Two other questions. Will those kill my snails and can I run the flatworm exit with my fish in the tank?

 

[ReefEngr]

No, they won't kill your snails. As long as you follow the instruction, flatworm exit is safe for fish, corals and inverts.

Thank you reefengr. I really appreciate it.

Fw s do release a toxin when they die so i would suggest u siphon as many as possible before treating .
