The addition of live prey may have introduced parasites into your aquarium. It is also possible it was pre existing and an unknown stressor may have triggered active infection. Regardless, now you have to treat. Check water quality first. Poor water quality is a major cause of illness and it can also complicate any condition. Test a sample at home with a kit or submit a sample for testing. Most pet stores or aquarists will do this for free or for a nominal fee. Ammonia and nitrites should be 0 ppm (parts per million). Nitrates should be 40 ppm or less but for HITH, try for 10ppm or less. Perform partial water changes using aged or conditioned water that is temperature and pH matched to prevent shock and further stress until water parameters are acceptable. Metronidazole is the treatment of choice for HITH. It will kill Hexamita which is the parasite associated with HITH. You can purchase metronidazole for tanks online or in the aquarium section of most pet stores. Follow label directi

Is it possible to keep wild caught saltwater fish as pets?
Yes it is possible, however, unless you have a lot of experience keeping saltwater fish, please do not even attempt it. Most wild caught saltwater fish will not feed when they are in an aquarium, and only a small percentage will ever learn to feed. Please leave them where they are happy and healthy and where they belong, the sea.

If you can get him into a separate tank, that may be helpful. Remember though, a rapid change in nitrates can be just as dangerous as elevated nitrates. Maintain temperature and oxygenation. Use an air stone or bubble wand if necessary. Perform another partial water ( no more than 30% total volume) in a couple days, then again in another 2 days to gradually reduce nitrates. Live plants will also absorb some of the nitrates. There are also commercial products that can be used. Only one method of treating the tank should be used each day to prevent a rapid decrease in nitrate levels.

What is disease in parrot fish in gill in this picture shown are , and How to treat them ?
Thanks for reaching out about your parrot fish and including a picture. Unfortunately the picture does not help to identify the lesion. There are multiple parasites (and different treatments) that can infest the gills, but very few are visible to the naked eye. Anchorworms would be one such parasite. A short (5-15 minute) fresh water dip can help to decrease parasite loads. Fresh water should be well aerated with an airstone, and monitored the entire length of the treatment. A visit to the veterinarian would allow a gill and skin scrape to identify the parasite, and therefore prescribe a more precise treatment. Good luck.
