Surf through your local Craigslist weekly you should/might find one on their for cheap although around me everyone is trying to get face value for them (I paid 200 for this tank brand new had it for 3+ years asking 170 ) I pass those ones up instantly lol
Not weekly, check hourly or more. Bookmark "fish tank" "fishtank" "aquarium" in "all for sale/wanted" and "all community". Also look for Petco $/gallon sale (40 breeders are awesome, but it can be expensive to get stands and lids) and local store once a year sales. After christmas, check walmart and other places that have package deals for discounted kits. Also join all "local" (distance you can drive) aquarium societies and read their boards and go to their auctions and swap meets.
casual mention your desire in each of your circles and/or on facebook. You'd be surprised how many empty tanks are sitting in garages and basements "too good" to throw away but not worth selling. Maybe you will get lucky and someone will "loan" you one.
Your dad may be afraid of a spill or being stuck with a tank when you leave home, or just think the home is too crowded already. Start planning you dream tank for when you have your own place, just don't buy any more fish that you can house right now.
wow people still reply to this.lol.anyway i was just asking then but it seems i might be getting a new tank for my goldies but might not need to check locally and thanks for all the replys.just asking how old do you think my 2-3'' ryunkin is?
