Be careful with Petco's 40g breeders if you are thinking of drilling it. They are now using a thinner glass and the bottoms are tempered. I went to buy one at the last sale and left without a tank. Make sure you check them.

As long as you are drilling the back or sides they will still work. If you are drilling the bottom then double check for that little white tag under the bottom glass that says TEMPERED on it. You can still buy 40g breeders that use the thicker glass and non-tempered bottom but it appears that Petco has changed a supplier (or their supplier has changed their design) and they can no longer be used for bottom drilling.
Smaller sized tanks still have the non-tempered bottom as well. Hope that helps.
