We just got a great deal on a 55 gallon setup off of craigslist.org.....tank, lights, filter, heater, bubble bar, gravel, stand and some extras for $150!!!! All almost brand new! Anyway, we got it setup and running last night (no fish in it yet) and was wondering if yall had any tips for us? We have 3 balas in a 30 gallon that we are going to put in this new one (they are going to much happier!)
