So, I had noticed Andrew's fins disappearing for a few days, and thought he was biting his tail. So I did a few 100% water changes and added some salt, and his tail seemed to be growing back just fine. Then, yesterday, I did a 50% water change, and thought he would be ok. After I finished changing his water, I turned his light on so I could see him and the tank and make sure it didn't look gross, and he was flaring at everything and anything. While he was flaring, I started freaking out because I noticed that his fins were not just fine. He has holes missing, and they're all frayed! They didn't look that bad before I did the water change, and as I was watching, it looked like there were chunks of his tail falling off of him! I'm so sad, and I want to fix it, but I don't really know my next step. =[ Today, his tail looks even worse. Here are the details that I know:
5 gal. minibow tank (not cycled, I don't know how to do that) with a filter and a heater kept at 80-82f, 4 silk plants, gravel, that's all the decorations.
I don't know the water specifics, but I will go get some water tested at the pet store and let you know after I do that.
I've had him for almost 2 months, and he's my only fish.
I just changed my filter yesterday when I changed the water.
My tank gets natural sunlight, but only partially, during the day from the window across the room.
I change my water once a week usually, but I've been changing it twice a week since his fins started falling off (before I noticed the holes missing).
I only just vaccuumed the gravel last night because I just got the gravel vac last night. Before that, I was doing it by hand, taking Andrew out and emptying the tank, cleaning off all the plants and gravel. Long process.
I feed hiim once a day, in the morning, 3 pellets. Once, my boyfriend fed him like 10-15 because I wasn't there to tell him no and he didn't know any better; that was before the fins started being funny.
I attached some pictures, I hope they are clear enough, and sorry if they are big I don't know how to change the size.
