One of my guppys has all these white bumpy things all over him is this normal or an infection of som

Symptoms

If your fish

1) Have white spots on the side,

2) Fins are folded and show white spots,

3) Eyes are cloudy,

4) Breaths at the surface,

5) Show behavior of loss of appetite, hiding,

it is very possible to have Ichthyophthirius multifiliis, or ich, on it, which is a species of ciliate protozoa which parasitizes freshwater fish.

Treatment

1) Three phases of ich's life-cycle (Adult, Cyst, Free swimming) take about 4 weeks at 70潞 F to complete but only 5 days at 80潞 F. For this reason it is recommended that the aquarium water be raised to 28 to 30掳C (82 to 86掳F) for the duration of the treatment. Avoid fast temperature changes; water temperature should be raised or reduced gradually 1-2掳 per day. There are species of fish that will not tolerate the high end of temperatures needed to be effective. If the fish can stand it, raise the temperature even higher up to 86潞. Raising the temperature also presumably reduces and kills the free swimming parasite.

2) In small tanks, the most recommended method of treatment for ich consists of adding aquarium salt until a specific gravity of 1.002 g/cm鲁 is achieved, as the parasites are less tolerant of salt than fish. This is not practical in ponds because even a light salt solution of 0.01% (100 mg/L), would require large quantities of salt (272 lbs/acre-foot). Fish can be dipped in a 3% (30,000 mg/L) solution for thirty seconds to several minutes, or they can be treated in a prolonged bath at a lower concentration (0.05% = 500 mg/L). Salt at low concentrations (0.01 to 0.05% solution) is an excellent means of controlling "Ich" in recirculating systems without harming the biofilter. Guppy is a salt-tolerant fish.
