they were doin very well and looked healthy until out of nowhere when i went to feed them tonite!!..they had some whitish dots on them but it did not look like ick!?..i put some aquarium salt in in case it is a parasite problem (they are about 7 months old) ((i have a pond in my back yard which i raise rosy reds in so they arent fed to the piranhas directly from the pet store aquarium))
Answers:
the white dots are called white spot . have you cleaned the tank out lately they can get it from shock or have you bought new fish it could of bin a disease on it go to your local pet shop or pets st home and theyll have a product called white spot controll
Ich or “white spot disease” is the most common disease affecting freshwater tropical fish. It is caused by a protozoan parasite, Ichthyophthirius multifiliis, that multiplies rapidly, causing devastating and rapid death within the aquarium. Ich feeds on the skin and gills, providing sites for infection by other organisms, such as bacteria and fungus. In addition, the resulting holes in the outer layers of the fish make it difficult to maintain the proper concentration of salts in the body.
Any stress on a fish results in a reduced immune response and increases potential for infection. A few of these stresses include poor water quality (elevated ammonia or nitrite, sudden temperature changes, or low dissolved oxygen), poor nutrition, crowding, improper social structure, and aggression. One of the most common causes of ich is introduction of a new fish into an established environment without adequate quarantine.
Symptoms
Ich appears as small, white, raised spots, similar to grains of salt, on the skin of your fish. These spots are actually the adult stage of the parasite known as the trophont, which is enveloped in the pus and tissue of the skin and slime layer. In addition, infected fish display one or more of the following symptoms:
Increased mucus or slime on the body or gills
Darkened appearance
Hiding in an unusual or atypical location
Flashing (rubbing their bodies against a surface)
Rapid swimming and breathing or gasping at the surface
Slow movement (as the disease progresses)
Diminished appetite
Ich Life Cycle
Trophont (the feeding stage): This is the only stage seen by the naked eye – as the white spots on the fish. The mature trophont burrows under the skin and feeds on the skin and gills. It is well-protected from treatment chemicals.
Tomont (the reproductive stage): After infecting the fish, the trophonts fall off into the gravel and become encysted in a free-living dormant stage. Then they divide into hundreds of tomites.
Tomites (larval stage): Tomites are free-swimming larvae that can survive for about 4 days without a host, although they may be infective for only a portion of that time. It is this stage that is most vulnerable to chemical treatments in the water.
Theront (the infective stage): Tomites mature into theronts, which invade the fish by burrowing into the skin and gills and penetrate within 5 minutes. Here they feed on cells and tissue fluid until they mature into trophonts and begin the cycle all over again.
I wouldn't like to be fattened up and then fed to piranhas!! Something has had too much sunshine here I think.
Raise the temp to about 95 degrees and treat with antibiotics. Hopefully, they will survive. These fish survive a lot in the wild..mud ponds, high heat, etc.
I don't know what these fish are, but whit dots sounds like white spot. Its a fungal infection, and it really gets a hold when the fish are under stress. Check the water quality and temperature.
What is an rbps?
