I really liked this little six line wrasse that I saw in the pet store. After coming home and researching I decided he would be a good addition to my tank.\n\nEither I wasn't observant enough or something happened in transport or introduction to the tank because I noticed after a day that half of his tail fin was missing. My daughter thinks it's an uncanny coincidence since we tried to take her and her friend to see the Dolphin Tale movie this weekend and they were sold out. She thinks it's our destiny to save the little fellow...and I don't disagree.:h5:\n\nI turned off my protein skimmer and began dosing with Melafix. I have a 45 gallon tank and I plan to dose with 4 tsp per day for 5-7 days and do a 25% water change. \n\nDoes this sound like the right approach? He is eating and swimming around okay. When I turn my protein skimmer on after the water change, what can I expect?\n\nHow long will it take for the tail to regenerate? \n\nShould I continue treating the tank after the first week?\n\nI appreciate any feedback.
