Thanks, Bl33dy.
Unfortunately, there was an outbreak of ich in the tank.
I've been ridiculously busy with school, and now I'm getting sick, so I haven't gotten the chance to buy any ich meds. All I was able to do was raise the temp to 82.
I'll see what happens with the fish. I've only seen the ich on the tetras, not the rams. If they all kick the bucket, then I'll more than likely just add some cherry shrimp in there for a while, until I figure out what to do. I could always just add the betta and some rasboras. I'm hoping the rams and the majority of the tetras make it through.
