looking to upgrade tank

[JaiWiz]

I got a 55 gallon now and it is too small for my fish. i wanna upgrade to a 90 or 100 gal. and slowly set it up so when it's ready i can just move everything from one tank to the other i did'nt really wanna spend any more then 200 on the tank as i will have to buy another canister filter and build a stand and make it look pretty cuz my stand now is a eye sore and figure out something for lighting. I just bought a house, appliances and soon to be furniture so my budget is very very very cramped and everytime i talk about a new tank my fiance reminds me how if i get something she gets to pick out whatever furniture she wants. If you just said "Oh ****" welcome to my world lol thanks guys
