If you breed you are likely to end up with a fair number of snakes, and tanks SUCK when it comes to cleaning, not to mention they take up a tonne of space.Well she's already got a tank,
I made the switch to tubs early on and have never looked back.
Also remember each python needs it's own tub, and that you need to be prepared to house, feed, heat and otherwise care for any snakes you breed that you cannot sell.
OH, and one more thing...every year, as the market becomes more and more saturated with morphs, those morphs come down in price to reflect supply/demand. Meaning that to make money, you need to invest a fair bit to get a profitable snake...and by the time they are breeding they may not be so valuable. I know a fellow who bought a pair of Pastels back when they were still fairly expensive...and he never made back what he bought them for, and finally sold them dirt cheap. He had a financial loss on that pair.It happens.
