I bought my betta fish Sam three weeks ago from a local Pet Co. Sam is a male, half-moon double tail plakat (if that matters.) It was my first time getting a Betta fish since I was a child and it didn't take me long to realize that there was something wrong with his fins. I noticed that pelvic fins had a silverish look to them and after a week I was sure that it grew. So I started to read up online about Betta fish and eventually found out about fin rot. I google imaged pictures of fin rot and it looked exactly like what Sam has.
I found this website http://www.petfish.net/articles/Bettas/finrot.php
and bought the Jungle Fungus eliminator online off of Amazon.
I have followed the instructions and given Sam three treatments (his third yesterday) every fourth day. At 1 teaspoon for the 2.5 gallon tank. However, his fin rot looks like it is getting much worse and I am getting more worried. His bottom fin that is long and connected now has a split in it and the top fins look like they are rotting also.
He has two fake plants and a little rock thing to hang swim around in his tank.
