My flower horn has ducklip, dark horn, and peeling skin. How to treat?

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 directions carefully. Remove the charcoal from the filter during treatment. A broad spectrum antibiotic should also be used to prevent secondary infection. If you have other fish in the tank, monitor them for similar symptoms. A proper diet is also critical. A vitamin and mineral deficiency may predispose a fish to this condition. Use a fortified pelleted diet. You can soak food in garlic juice (or GarlicGuard by SeaChem) to boost the immune system and stimulate the appetite.

This is a quite generic but concerning presentation. Begin by submitting a water sample for quality testing. Most pet stores will do this for free or a nominal fee. Clinical examination should always include a water quality check, even if you have done so already. Water testing should be performed with a quality test kit, measuring NH4, NO2 and NO3. High ammonia levels, PH imbalances may be responsible for these signs. Oxygen concentration and quality of the filters should be determined as well. If water quality is good and there are no major imbalances, your fish should get examined to look for any sign of bacterial/fungal infection and eventually water should be treated.

Separate him out into a hospital tank if possible. He could be injuring himself on tank furniture (plants, rocks, etc.). You can treat using a broad spectrum antibiotic such as Maracyn or Kanaplex. Find them in the aquarium section of the local Petco or fish store. Plain aquarium salt (NOT table salt) can also be used to aid healing. Dissolve 1 teaspoon per gallon of water in a cup of tank water and gently pour it into the tank. Treat for 7-10 days then perform partial water changes to decrease salinity. Use only aged or conditioned water that is temperature matched to prevent further stress or shock.

It needs to be separated into a hospital tank by itself so it can be treated and heal. If you leave it in the main tank, the others will continue to pick and nip until it dies. Maintain pristine water quality and chemistry during treatment. You can use a broad spectrum antibiotic for 10-14 days to treat infection. You can find one, such as Maracyn 1 or 2, Kanaplex or Furan, in the aquarium section of the local Petco. Follow label directions carefully and remove the carbon filter insert during treatment if indicated.

Thanks for reaching out about your Oscar and including photos, but difficult to see the HLLE lesions due to too dark. The eye looks terrible and systemic antibiotics are recommended at the least. A veterinary visit is highly recommended to clean the wound and provide other possible treatments. The water quality must be kept pristine (pH, ammonia, nitrites, nitrates) to assist recovery. Antibiotics added to the water do not penetrate into the body, nor do fresh water fish drink, since osmotically water enters over mucous membranes (gills, mouth, skin) and antibiotics do not cross this barrier. HLLE causes can be multi-factorial including water quality, bacteria, parasites, carbon particles in activated charcoal (filters), low vitamin C, etc. Check and correct water quality, replace existing food if older than two months (vitamin C degrades quickly), see a veterinarian with fish experience. Good luck.

Perform a partial water changes, 30-50%, using conditioned water. Dissolve 1 teaspoon up to 1 tablespoon of Epsom salt per gallon of water in a cup or two of tank water and gently pour it into the tank. This will work as laxative. Fast the fish for 3 days, then start feeding bits of cooked and shelled green peas until defecation and appearance are normal. You can also add metronidazole at 200mg/20 gal to the tank. Repeat the water change, salt and metronidazole every 3 days for 3 cycles. Be sure to treat only the amount of water being replaced with salt and not the entire tank volume. Remove the carbon filter insert during treatment as well.

Thanks for reaching out about your cichlid and including photos. This is probably not an abscess that can be treated with simple antibiotics. A tumor or possibly a fractured mandible bone causing inflammation. A veterinary visit is recommended to assess, possibly requiring radiographs. If it can not open the mouth and can't eat, then it will starve. Check and correct water quality for pH, ammonia, nitrites and nitrates. Pristine water quality will be needed to assist in recovery. Good luck.
