Got some jewelers handheld magnifiers today and noticed some dots on my 10 gallon mangrove tank that is plumbed into my system. On closer look they are flatworms
I checked my other two tanks (8 gallon and 35 gallon) and couldn't see anything on the glass/rocks/corals and then I realized I have a pair of mandarins in the 35 gallon and an azure damsel in the 8 gallon and they eat flatworms. Guess I'll be buying a new fish for the mangrove tank that eats flatworms!
I don't want to use chemical treatment to tackle the flatworms perse but in theory if I turned off the return pumps could I add flatworm exit to just the sump and keep it circulating since in theory the tanks will all have fish that eat flatworms to make a decent dent in the problem?
Pictures for reference. Guessing theyre not the really bad kind as all the corals look great and are growing.
