Why do parrot fish in an aquarium lie at the bottom

Parrot fish are very resistant to external viruses and are successfully treated against them, but their own infections are difficult to diagnose and treat.

If dark spots appear on the body of the parrot fish, do not be alarmed. This can be due to poor water quality (increased nitrate levels), or due to the stress the fish have suffered. Test the water in the aquarium and, if necessary, change 30-40% of the volume and siphon the soil. Usually substitutions help and the spots on the fish gradually disappear.

If the parrot fish lies at the bottom and swims poorly (poisoning, overeating), this procedure helps: add methylene blue to a blue color into the jig (12-15 liters), dissolve half a metronidazole tablet and 0.5 g of kanamycin there. There should be good aeration during treatment. You can feed a parrot with a bloodworm that has passed a 20-minute quarantine in kanamycin – 0.5 g per 50 ml of water. It is better to change the water in the jar every day and re-inject the full dose of the medicine. Improvement in this case occurs in 3-5 days.

If white grains (such as semolina) appear on the body of a parrot fish, it is a sign of ichthyophthyroidism.

The treatment is best done with Sera costapur, it does not change the balance in the aquarium. First, you need to siphon the soil, replace 1/3 of the water, rinse the filter. Since this medicine decomposes in the light, it is necessary to pour it into the aquarium at night, after turning off the lighting. The amount of the medicine is taken depending on the volume of water strictly according to the instructions attached to Sera costapur. The agent is applied every day with a preliminary change of 30% of the water volume until the traces of “semolina” on the fish are completely destroyed. The treatment usually takes 5-7 days. During the entire treatment, you need to feed the fish minimally. During the treatment, it is recommended to raise the water temperature in the aquarium by 1-2 degrees, but not higher than 28 ℃. Don’t forget about constant aeration. If there are fish other than parrots in the aquarium, then the treatment is carried out with half doses of the medicine. Small fish, such as neons, cardinals, small tetras, rasbora, as well as scaleless catfish, synodontis, botsi, loaches, loricaria, do not tolerate the full dose. Even such a small dose of medicine is not tolerated by Platidoras. The half-dose treatment time is, of course, increased.
