Great info everyone. I currently have both a sixline a yellow coris wrasse working on my red flatworms, not sure if they are eating it or whether they can keep up? I think it is hit or miss, based on the specific individual wrasse. Definetly worth a try. Last night I siphoned out several hundred, and things look decent. The good news is that these flatworms aren't really harmful, just a nuisance to look at. I would be interested to see how the blue velvet nudi does. They are pretty cool looking too!
Thanks chuck for all the info on the AEFW, thankfully these guys aren't in my tank.
I have had these red flatworms for some time and didn't notice. I hope others don't have these, as they are easily mistaken for small flecks of brown/red flake algae. If you look closely they move slowly, have a red head and a whitish-coloured tail. They can easily hide on frags or rocks from others tanks. Moving foreward, I think I will be giving more attention to quarantine or Coral Rx dipping practises.
