i went to my lfs and they are relocating and they were selling 15 gallon drilled tanks for 5 bucks with bulkheads so i picked up 4 of them dont know were im gonna put em but i have them just incase.
I did the same thing a few months ago. I now have 4-15's 4-20's 2-40 breeders and 2-75's......almost forgot the 2-110's and 1-125 All for less than $200
