Yea, you definitely need to invest in an additional tank. Have you checked out craigslist? I'm picking up a 55 gal with hood, heater, filter, air pump and stand for $35 tomorrow. Best deal yet. Normally I get just the tank and hood for $40-50. I've got 5 55 gal tanks already and the total cost for all of them has been right around $200. I find smaller ones (10's and 20's) for free quite often, but I have more than I can handle of those at the moment as it is.
Just to give you an idea, I've currently got 900 1 inch fingerlings in a single 55 gal tank, 700 2 week old fry in a 20 gal long, 300 2 inch fingerlings in another 55 gal, 30 3 inch fingerlings in a 29 gal and 45 5 inchers in a 45 gal hex. I also have another batch of about 500 fry getting ready to turn into "swim up" fry in my hatching jars.
If you can get a workable system going asap, you'll have no shortage of fish by springtime.
12 ac pond in NW Missouri. 28' max depth at full pool. Fish Present: LMB, BG, RES, YP, CC, WB, HSB, WE, BCP, WCP, GSH.
