I've looked through the different threads on flatworms, but haven't really seen one that addresses my problem. I will be doing my first frag swap soon and really don't want to contaminate anyone else's tank. Up till now, I've had no visible aptasia and only a few spheres of bubble algae that get removed on site. However, I just noticed flatworms on my tank's glass this last weekend. I say mine are unusual, because photos I see on here have them looking orange-red and almost circular. They also look rather large. Mine on the other hand are very small (even the largest ones would require 2 to 3 to equal the diameter of a penny) and are brownish. I used flatworm exit on them on Sunday. However, it didn't eliminate them as was mentioned in the directions though it did knock down the population a bit. I dosed the tank again tonight with about twice the dose (48 drops for 30 gallons), and still I have survivors. Doubling the dose actually made my micro brittle stars look quite unhappy. To account for possible resistance to flatworm exit, I plan to triple the dose on Thursday to see if that eliminates them. I also siphon whenever I see one. My question is, do I need to go through all of this? Are my flatworms benign compared to the ones I mentioned before? Again, I really don't want to develop a reputation of providing frags that have pest included so any help with be much appreciated. Thanks so much! I also included a photo to represent what mine look like by the way.
Unusual flatworms. Should I be concerned?
