To prevent this disease from occurring with your other fish, you need to minimize the amount of live foods that your fish eat. This is due to the fact that the bacteria which causes Dropsy can often live in live worms and other Betta snacks.

External Parasites

This means that your fish is generally going to be darting around the tank and trying to scratch itself on anything that it can find. This will include the sides of the tank, decorations, and plants. With this problem, the parasite itself can often be hard to see which is why the fish’s behavior is important.

ICH / ICK (Ichthyophthirius multifiliis) or White Spot Disease

The protozoan parasite known as the Ichthyophthirius multifiliis can be found in most freshwater fish and aquariums with the exception of those using UV filters.

As the name of this disease might suggest, the symptom will be white spots appear on the fish. These sports will often look like salt grains and appear all over their body. Your fish might also clamp their fins to their side or start to move slowly. However, there are some fish that start to dart around the tank and will rub against the sides with this disease.

White Spot Disease can generally be transported by new fish, plants or equipment being brought into the tank. If you feed your betta frozen live food this is also a form of transport for ICH. ICH parasites are very sensitive to heat so if you maintain your betta fish’s tank water a nice mid to high temperature (80ºF/27ºC) you probably will not have to deal with ICH. When the temperature is below 80ºF there can easily be an outbreak of ICH which is highly contagious so treatment should be done in the whole tank.

API General CureTreatment

This highly contagious disease is caused by a parasite and treatment of the entire tank is recommended. One way to do so is by draining the tank, washing it with a copper sulfate solution and thoroughly rinsing it.

You can also use a product known as BettaZing (or similar) and when doing so you do not need to empty the tank. This product is great when it comes to treating not only Velvet but other diseases known to bettas. It is also recommended that your tank be kept somewhere dark so the parasite does not receive any light and is easier to terminate.
