Male Betta Fish: Brown, Rotting Fins?

Question

I have had a male betta fish for almost two weeks and he was perfectly fine and blowing bubbles. Starting from two days ago, he's starting to slow down his movement. Just today, I saw him in his plant with a couple of brown marks. His colours were originally red and blue but his fins are partly browning.

I need help!!! He's really freaking me out.

How do I cure this?

Answer 1

Clean his water EVERY DAY as you treat him with mediciation (available from your local pet store) for fin rot. A betta fish never gets fin rot when he always has healthy, clean water to live in. You must learn how to take care of a betta properly.
