Sick Fish :(
I have a sick beta. I have had his since last August. He randomly does this not eating thing but usually it only last like a week. I give him less food and then he will go back to normal amounts as the week progresses. I was cleaning his water and noticed that his fins (all of them) looked veiny and blood shot and kinda frayed. So I looked it up on the Internet and i think that it is Fin Rot. I bought some Maracyn-two but the packets are for ten-gallon tanks and i keep him in a one-gallon tank. Should i just use like a few sprinkles of the powder or what?
