Common Diseases of Blood Parrot Fish and How to Treat Them

1 White Spot Disease (Ich)

A very common disease in all fish, caused by the parasite Ichthyophthirius (white spot). Infected fish show scattered white spots and often rub against objects. Without treatment, the body fills with spots within days and worse follows.

Early ich in blood parrots is easy to treat with higher temperature. Raise water to 28°C; within days the parasites burst and fall off. Then change water appropriately and hold that temperature; the fish recovers soon.

2 Black Spot Disease

Caused by many factors — fright or poor acclimation after water changes — but spots usually fade soon. Still, avoid large water changes and startling fish, which easily cause illness in any ornamental fish. Keep water stable, avoid shocks, change water reasonably, and maintain constant temperature.

3 Head-Hole Disease

Common in LuoHan and blood parrots, with high mortality. Early signs: whitening and slight swelling on the head, then holes. Usually from vitamin, calcium, or phosphorus deficiency, or parasites blocking nutrient absorption. Isolate the sick fish at once, squeeze out the pus from the head, clean the abscess, apply metronidazole powder and erythromycin ointment, then bath the fish in a small basin with wild yellow powder — but match the bath temperature to the tank.

4 Enteritis

Symptoms: noticeably swollen abdomen, protruding red inflamed anus, white feces. Overfeeding can cause it, so feed small amounts often. If the fish won’t eat, is weak, hides in a corner, and passes white feces, treat with an appropriate dose of a broad-spectrum antiparasitic fish tablet or furazolidone for about three days; it usually improves.

Bacterial enteritis is harder to treat. Signs: clamped fins, clustering, darkening, bloating; can be fatal. Treat with a norfloxacin bath and stop feeding until bloating subsides, then change water. If accompanied by clamped fins, darkening, and fin rot, first use oxytetracycline, copper sulfate, and salt to reduce inflammation.

Parasite infection can also cause enteritis without appetite loss; feces are segmented or hollow. Use metronidazole plus furazolidone to expel parasites; stop and change water once large amounts of white feces pass.

Finally, enteritis from water-quality problems usually needs no treatment — just adjust the water and let the fish rest a few days.
