Keep in mind when setting up a tank blood parrots (I'm assuming you mean the hybrid fish and not the authentic parrot cichlid) are big, fat fish, and so need reasonable sized aquariums, nothing less then 40 gallons for an adult is best.
Even tropical fish can handle temps of less then 70 for limited periods, but naturally they should be kept in water between 75 and 80 on a regular basis.
Here are my suggestions
•Start off with a larger tank, you won't regret it. More water volume means a more stable aquarium. More space means more room for more and/or bigger fish, and more space for plants to grow in. Check out the 20 gallon long style tank (12x30" footprint) it's an excellent smaller sized tank.
•Avoid UGF filters. They are outdated. They make great biological filters, but they can't be cleaned. Over time dirt and sludge builds up under the filter plates and causes a degradation of water quality. Power filters are pretty inexpensive, very effective, and easy to maintain. Since the only part of these filters that are submersed is the intake tube, they don't take up valuable aquarium space either.
•From the fish you want in the tank I also suggest avoiding Neons. There are better choices of schooling fish that are more hardy and tough enough to handle the more aggressive fish you are looking to put in the tank (betta's, gouramis, blood parrots...)
