I am pretty sure that the petco dollar per gallon sale ends tomorrow. We just got back from petco and I got 2 40 breeders. I am not going to set them up until the shed is built. My original plan was to have 6 40s, but i decided that I didn't need six and that 4 would be good. I have 2 40s that are already set up that I plan to move. I have 3 lionhead goldfish in the bottom 40 and 3 small electric blue haps in the top 40. I am going to keep the goldfish in the bottom 40 and move the haps to a 55. I already have a 55 and it is currently empty. I am going to use the 2 new 40s for breeding discus.
