Notice if your fish’s fins look clumpy or your fish is not as active as he usually is. Your Betta may also have a paler hue than normal and white, cotton-like patches on his body. These are all signs of a fungal infection. Fungus can grow in tanks that are not treated with salt and Aquarisol once the tank water is added.
- The fungus can spread quickly from one infected fish to the other fish in the tank so it should be treated right away.
- Once your fish suffers from kidney failure as a result of fluid buildup, your fish will likely die. You can prevent your fish from contracting dropsy by not feeding him live worms or contaminated food. Aquarium salt baths can draw out fluid, and medicines can help. Since it's hard to know what medicines are appropriate, and usually dropsy worsens quickly, painlessly euthanizing is acceptable.
- Luckily, most Betta fish can regrow their tail and fins if rot is treated in time. However, your Betta fish’s tail and fins may not be as vibrant as they once were when they grow back.
- Some Betta fish can contract advanced body and fin rot when a case of regular fin rot goes untreated for a long period of time. Your fish may lose his fins and body tissue as the rot progresses. Once the rot eats your fish’s body tissues, it can be difficult to cure the advanced rot and your fish will essentially be eaten alive.
- As velvet is a highly contagious parasite, you should treat all the fish in your tank if one fish shows signs of velvet.
- Keep in mind swim bladder is easy to treat and does not hurt your fish, so you do not need to worry about your fish dying due to swim bladder.
- Your fish may also scratch against objects to try to remove the anchor worms, and the points where the anchor worms are attached to your fish may be swollen.
