There are various diseases that can affect your betta. Most betta fish diseases are caused by poor water quality, so you can prevent many by keeping the water clean. Some of the most common illnesses include fin rot, velvet, and popeye. This article will discuss some of these illnesses.
Fin Rot
Fin rot is one of the most common diseases. If you keep a betta long enough, you will probably have to deal with it at least once. This condition is characterized by the tail or fins rotting away. It can quickly become a problem if you allow the water to stay unclean too long. Although the tail or fins will grow back once treatment begins, it will take some time.
Popeye
Popeye is also one of the most common betta fish diseases. Like fin rot, it’s caused by unclean water which leads to a bacterial infection. This condition is quite easy to spot as your fish’s eyes will literally bulge out of his head. It can be disgusting the first time you see it. Popeye needs to be treated with antibiotics and frequent water changes.
Velvet
Unlike the two aforementioned diseases, velvet is caused by a parasite. It is highly contagious and can quickly spread to other fish in the tank. Affected fish will attempt to get rid of the parasite by rubbing themselves against hard objects. Other signs of velvet include rapid gill movement, weight loss, loss of appetite, and lethargy.
This illness presents a problem because it’s usually diagnosed in an advanced stage. Therefore, you would need to start treatment as quickly as possible. TO treat this condition, you will need to dim the lights, add copper sulphate to the water, and raise the temperature to 80 degrees Fahrenheit. Your fish may also have a hard time breathing. Aquarium salt will help remedy this.
Dropsy
Dropsy is one of the most serious betta fish diseases. It is usually fatal. This illness results from kidney failure which causes fluid to build-up inside your fish. You can easily spot his swollen belly. If he also has raised scales, it’s a pretty safe bet that he has dropsy. Unfortunately, there is no cure and most bettas die within a couple of weeks.

I spaced the links because I cannot post a link on this website it seems. so please try to glue them together when you access it.
All Links Work. PLEASE TRY AGAIN.
Links don’t work.
Edit:
OK, got the links to work. (Thanks Maddie.) If that’s really a Pleco, and it’s still alive, you need some serious treatment, and in a hurry. It’s got to be some kind of fungus, but I’ve got to say, I’ve never seen anything so horrid before. Poor fish. It might be most humane at this point to euthanize the fish. Google “fish, euthanization, clove oil” if you choose this route.
Otherwise, get a good general fungal treatment in the very near future and treat the ‘ell out of that tank.
In the future, please look into treatment before it’s gotten anywhere near this point.

How do you treat white spot disease(Ich)?
About a week ago My black molly was hanging around the bottom of the aquarium. He would come out to eat but that was about it. I noticed a white, looked like a scratch on his side. Been keeping an eye on it. It hasn’t gotten bigger or worse. Well tonight I found a couple of more white spots on him. When I got real close to the tank I noticed they where not scratches they where on the outside of the skin. So I looked at some pics online. How do I get rid of this. I am going to Petsmart in the morning. What do I need to get? None of my other fish that I can tell have any. The molly has not been scratching himself on the bottom. Tonight he has been swimming funny though. I was going to clean my tank this weekend. Do I need to put this off till I get this cured?
