You certainly could try but here is a small example...
Pair of Leos is what $2,000?
Tank is $500 at the least, say you get a cheap used one...
Filtration/Heating would be $200 at least...
Food - $5 a week or so - I think should cover it...
Utils - $10 a month or so depending on cost of power/water in your area
Supplies - Prime for water changes, Misc Filter floss etc... $20 a month
Tank to hold pups in when they do breed is more $$$.
These are all random numbers and it's been a long day at work but I just felt like crunching numbers...
Initial investment of $2,700 for the Rays and Tank.
Monthly cost of $40. so $480 a year.
In the first year you'll spend $3,180.
If you get lucky and have a pup within the first year and it survives and you sell it for $1,000.00 you'll only be down $2,180.00 at that point.
In another year you have two and make $2,000.00. But you're still down $2,180.00 so getting closer to even at $180 in the hole. Oh and the cost of keeping them going is another $480 for that year, now you're $660 in the hole.
Another year passes and you spend another $480 in supplies/power/water that year. Debt is back down to $1,140... However you breed two pups but want to keep one or one dies, so again you only sell one for $1,000. Now you're at $140 in the hole again.
and this isn't considering the fact either parent could die at anytime. Something could break that needs replaced, etc...
So as you can see with this scenario over the course of years you never make a dime and mostly just lose money. I forget who but someone on here posted a new Ray pup recently and everyone jumps in saying "Man, I should breed Rays, easy $" and such... To which this poster replied with something like "I have been pouring money into these for years and this is the first Pup to survive". So obviously no matter what it sold for you're still in the hole.
If it was easy Rays would sell for $3 just like Convicts and everyone would do it. But it isn't easy and it isn't cheap and thus Rays are expensive and breeding them for profit is very hard.
Not saying anyone shouldn't try but just some basic thought would show it's not going to be easy or quick.
