My room mate and I have a lot of bettas (12, to be exact). They all live in separate tanks, 1+ gallons etc etc etc. Whatever. We've got basic betta fish care down. Those fish live like little aggressive kings (and 2 queens).
My problem is, while we were at Walmart buying replacement filter cartridges for our big tank, we saw what we thought was one male betta living in a cup with 2 dead crown tails. He had clearly been eating the other two. When we went to check out I asked if we could have him for free. They said yes.
We get, home, set up Hannibal in a nice new home, and go to flush the other two.
One of them is not quite as dead as we thought. He's named Beyonce (because he's a survivor), but he pretty clearly is sick.
I think it's a fungal infection (white fluffy stuff on his face, looks like a film over his scales; he kind of looks like he's peelings a little). His tail is an absolute mess from where Hannibal had been noming on him. He has a HUGE appetite and will eat until he looks like he's about to pop. He's living in a 1/2 gallon mug right now (not permanent, but we didn't want to buy a bunch of stuff for him, and then have him die.)
Time for the question:
What do I do to help him out? We've never had a really SICK betta fish before. I've been changing 100% of his water once a day. He's looking a little better, but somehow I doubt he's going to heal up well on his own.
Do I go with meds (and which ones)? Or do I try doing the salt whatever?
This is Beyonce. All of these pictures suck.
And for funnsies, here's Hannibal
