Green Polyps question


New member
I have a large green polyp rock that has had its perimeter tenticles on each polyp eaten by one of my fish. Do these regenerate, if I move it to different tank where won't be messed with?

As you can see they are slightly closed also from being picked at.

Aw man, those look rough. Move them out of there, give them a dip in Lugol's and keep and eye on them. The chewed up ones won't regenerate, but the ones that are the least damaged may perk back up. Good luck!

Lugol's or Iodine Dip... Lugol's is a concentrated iodine solution, 40 drops to a gallon of saltwater for no more than 7 minutes, should effectively disinfect a coral. Do NOT use this procedure on fish, although I've used it on Sea Stars with some good results. Do NOT dump the dip water back into the tank, discard it. If you're using something like Kent Tech - D or Seachem Reef Dip, follow the directions on the package. Those products use Iodine and Potassium Bromide and other compounds to achieve the same end - to disinfect corals of bacteria and other pathogens.

I have used this several times with no ill affects on my corals, keep a close eye on your corals as some tend to not like this.
