Lower the tank temperature to 76 °F (24 °C)

The life cycle of this parasite can vary dramatically and is dependent on temperature. Optimal growth of most strains of Cryptocaryon appear to be about 73.4–86°F (23–30°C), and they cycle faster in a warmer environment. A common mistake is to confuse the treatment of this protozoan with the treatment for freshwater Ich (Ichthyophthirius multifiliis). Raising the temperature of the tank does not eliminate this protozoa like it does with freshwater Ich.
Ideally the parasite would be eliminated while on the host or shortly after leaving the host. However, those that are buried in the gills are immune to treatment until they leave the fish. This along with the variability of the cycle makes it difficult to treat in such a timely manner.
To rid the aquarium of this protozoa, it is recommended that you use a combination of water changes and chemical treatment, a multiple number of times. A common mistake is to confuse the treatment of this protozoan with the treatment for freshwater Ich (Ichthyophthirius multifiliis).

Food intake by the parrotfish  varies seasonally and is determined by temperature, size and territoriality

PH should be maintained between 6.5 and 7.4, and kept at he lower end of the range if attempting to breed. Although they can be kept at a PH as high as 7.8, their colors are best at a lower PH. I know of a Parrot Cichlid owner who keeps his with discus, in very soft acidic water, and the fish look great. I keep my Parrot Cichlid's at a PH of 6.8 with a GH of 5 degrees and a KH of 2 degrees. Temperature should be between 76F and 84F degrees. I have had reports that a even lower temperatures will darken the colors of the fish, but this is not advisable. 10-20% water changes every 2 weeks are welcomed, as these fish produce plenty of waste and don't do well in toxic water.

Blood Parrot Cichlid Description Common Names: Blood Parrot ..

I've heard all kinds of stories and suggestions regarding Parrot Fish water temperatures. But no two comments agree. Formation of five biogenic amines in 6 iced, temperatureabused tropical fish, and in temperate water Atlantic mackerel was investigated. Spermidine did not change, while histamine, cadaverine, putrescine, and spermine varied differently in the tropical fish. Histamine was significantly higher in skipjack (Euthynnus pelamis), rabbitfish (Siganus oramin), and little mackerel (Rastrelliger kanagurta). Cadaverine and putrescine were significantly higher in skipjack and little mackerel but not in rabbitfish. Only histamine and spermine were significantly different in rabbitfish. Skipjack, rabbitfish and little mackerel are potentially scom-brotoxic. Parrotfish (Callyodon gutatus), barracuda (Sphyraena japonica) and scavengerfish (Lethrinus nebulosus) showed no evidence of potential scombrotoxicity. The 5 amines were higher in ungutted mackerel than in the tropical fish. Iced, eviscerated tropical fish have a much lower potential for scombrotoxicity than ungutted temperate mackerel stored under comparable time/temperature conditions.

Health Issues
Stress Spots: This is usually mistaken for Neascus (Black spot disease). Blood Parrots sometimes get Stress Spots which are black splotches on the body or fins and this is caused by stress. This is typically present you bring them home but can also show up when in cases of shyness, bullying, breeding, illness, or sometimes nothing at all. The splotches will usually disappear after awhile once the problem is taken care of.

Swim Bladder Issues: They show an abnormal swimming pattern, may even float upside down or appear to be stuck at the surface of the water, being unable to swim down, or they may lie on the bottom, unable to rise. Fish with a swim bladder disorder will continue to try and feed, showing a normal appetite. This is usually caused by a poor diet. To prevent this from happening it is recommended to feed shelled peas once a week for that days meals. This can also help with mild cases. For severe cases add 1 Tbsp per gallon of Epsom Salt into a container of water. Place the fish in the Epsom Salt bath for 20 - 30 minutes. This can be done twice a day but should only be done as a last resort. Ick/Ich/White Spot: is a common disease of freshwater fish. It is caused by the protozoa Ichtyopthirius. Ick is one of the most common and persistent diseases. Your fish will be covered with white cysts on the skin, fins and gills. Heavily infected fish looks as if they have been sprinkled with sugar and pepper grains. They may scratch themselves against gravel or decorations in the aquarium. Ick is usually deadly if left untreated. To treat ick it is best to first raise to the temperature in the aquarium to 86 - 89F. Then treat the tank with 2 tsp of salt per gallon of water or treat the water with Mardel CopperSafe. Any other treatment can potentially damage the Biofilter so other treatments are not recommended. During treatment it is not recommended that you change the water so before you treat the tank a 25 - 50% water change is recommended. Treatment should take 1 - 2 weeks depending on severity.
