After a devastating wipe out from ich, may I suggest a QT tank? I'm a hard head and I didn't think I needed one, but when you've got 4 or 5 fish in a 55g, like I did, one fish can with ich can wipe them all out in 2 days. Shucks, a 29 gallon with over-filtration is better than putting risky fish in a tank. If you read the post about army wife/divorce, you can see I found a great deal on a used 125g ($180) and now use my 55g for a QT tank.
