I recently bought my first Betta fish and I am very unexperienced. He was living in a small bowl for about 2 weeks with no filtration or heater (the lady at the pet store told me this was ok) then, I learned how cruel it is and got him a 5.5 gallon tank with a heater and filter. However, on his last day in the bowl I noticed a hole in his tail and I don't know what to do. :cry: I thought that transferring him to the bigger tank would heal it. He is swimming around and acting normal. I don't know how to help him, and I don't have very much money to spend on him. Did I make him sick by keeping him in the bowl for too long? :-( Please help!

You could try adding aquarium salt to his tank. It may help but it's hard to say. If it doesn't help....it could be a bacterial problem. Then you could try one of the antibiotics they sell at the aquarium store, it's about $14 and you'll have lots left over if you even need it again. I recently had an issue with the fins of one of my betta also, I tried a few things before eventually getting tetracycline and within a few days her fins were healed. (My fish was swimming around and acting normal too)

I noticed the problem after feeding my fish live brine shrimp from the store. I think maybe something came in the water.

Can you please fill out this form and post photos? It's almost impossible to give an accurate diagnosis without those and you wouldn't want to treat him unnecessarily.

Thanks!

I doubt you made him sick. Holes in caudals are often from flaring. And if you bought him from a pet store then fin damage is pretty normal. Honestly, if a fish is acting normal and eating I don't worry about them. I keep an eye on their fins but I don't worry.

I think it is a type of fin rot. I read it somewhere. That hole will gradually create a tear if untreated. Try salt treatment, melafix.
I prefer live food for my fish. They also had many problems with fins before. Nothing really cured them completely but after starting livefood, they was a big change. Try that if possible.

sometimes bettas can blow a hole in their tails if they flare too hard.

Most likely it's nothing to worry about and will heal up with some good clean water

Can you take a picture of it?

The pictures aren't working for me, I don't know why. I just made this account last night and I'm not sure how to use everything.

Okay, I will try the aquarium salt and see what happens. Thank you so much!
