I personally like to mix species but if you breed, inevitably you need to find new homes so some of the more popular species are always being bred as you can usually find a new home for the babies with little hassle. on the other hand, there are very rare species out there that others will breed to try and make significant money. Problem is, the rarity goes down each time you breed and that desirable species that you may have forked out significant money for, does not make the money you originally thought. Take T seladonia as an example, in the space of 6 months I have seen these go from nearly £300 a sling to £75 now. Still a lot of money but now the market is almost saturated with them and £75 can still be a hefty price for many to pay. Especially that species as they are renowned for being somewhat delicate and have unique care needs.
