@Vay: Definitely. From what I've seen in pictures, that's it.
@Saylor: It hasn't been running since March, as I had to separate the three I had into separate tanks. I had to put them into three smaller ones as I didn't have room to have the 10 gallon as well as a bunch of smaller ones. It's only been running again since I put the five females in together two weeks ago. I did some research and talked to the fish guy at my regular pet store about the 3-stages of Ich. That's a really helpful article; Thanks!
Gahh I knew I should have quarantined. Not doing that went against everything I know about animals.
Sounds like a heater is a must, huh?
So now that I've added the salt, how often should I add it and how often should I change the water? I'm guessing every day?
Should the girls be open or covered?
@AB1: Thanks anyway :)
