I can see why you're frustrating a lot of people. I, too, would suggest you slow down with your fish purchases because all of those fish aren't going to work in a 55 for long. Here is my story, which I hope might help. I started with a GT, JD, Texas and a Polleni in a 55, knowing I'd need a bigger tank, but assuming I'd have a while. They did fine for about five to six months. The Polleni outpaced everyone in terms of growth and started pounding on the Texas. I bought a 125 and moved them to the new tank. The Polleni still kept pounding on the Texas. Long story short, you can't count on anything, but definitely slow down so you can learn from experience at a gradual rate.
