This is Fernando. I bought him about a year ago at a Petsmart. He's a half moon betta, and has always been small.
With the recent 'end of the school year' stress, I pushed off cleaning his home far too often than not, and resulted in him dulling in color, not eating, and laying at the bottom for the most part.
Prior to about the last 7 days, I was getting a bit paranoid when I saw him floating near the bottom all the time, but his color was normal and he darted up to the surface whenever he saw my hand go for his food bag (flakes).
On Tuesday I went out to restock on items, and bought some Aquarium Soulutions 'Betta Revive health aid'. I've heard mixed reviews on it. Some people I see say it's worthless and does nothing, while others say it has done miracles for them.
I began treating him with the correct dose as instructed on the back of the package about 30 hours or so ago. He hasn't seem to have gotten any better, nor any worse.
Through my observation after researching betta illnesses for hours the other day, I believe he has Fin Rot. Many say to simply really clean all of his things and have frequent water changes, but I'm worried that he'll starve himself to death before his fins heal enough for him! Is there anything I can do that will aid him in healing faster? I can't run out or order any special medicine for him beyond what I have. Though I'll make plenty of money over the summer, my parents are penny pinching at the moment and gave me a hard time over buying the medicine I did get 'over a cheap little fish'.
This is what he looked like when I bought him. He didn't grow much if any, and after I began feeding him the flakes his body turned a teal color. (I somewhat question his gender, since I've rarely seen a bubble nest, he is small, and has shorter fins than most- however, I never saw the egg spot either.)
