Aquarium questions help?

Since I have a 10 gallon aquarium, but the fish are too big for her. My plan is to take it back soon. I wondered what would be a good idea to put there after i cycle. I was looking for some tanks for sale. I have seen beautiful 180 gallon which includes: Glass Aquarium with Corner-Flo filtration, glass canopy, wood canopy Prestige, Prestige Stand, 72 "120 Watt Dual Quantum bright fluorescent strip light, heat 200 to 300 watt Visi-therm, Stick the thermometer, the little giant 4 MDQX SC-1325 gph pump, Module II 2 Tidepool filtration, plumbing fittings kit, and Quick Setup Guide. 76 "x 27" x 67-5/8 "high. With a price of 2999.99. If I have 12 years of age, what I can do to make cash in whole or 4 months? 3: type of link http://www.drsfostersmith.com/product/prod_display.cfm?c=3578+3730+15520&pcatid=15520

There are many places in search of an aquarium would cost as much as 2999.99 is garage sales, flea markets, discount stores pet, craigslist, or just walking down the alley at the right time. I found a 30 to 55 gallon tank that way. (Cost to me = $ 0.00) Talk to friends, network a bit and see what he can reach before committing to plunk down that kind of retail price. For $ 3000, there are other worlds all fun items out there. Computers, HDTV, Motorcycles, etc by name but three. Be smart about it and good luck.
