just wondering if you guys know any. i posted past stocking for a tweny g long or 29g. but then my and my mom found out that a 20 high and iron stand would be the least pricy. im realy into live bearers and am seting up a ten gallon guppy tank. what would some good petsmart/petco fish be. under 4.50 a fish. PS i thought i had my stock planned out but now i hve to get a 20 high.
