How many jars/containers do you have to house each fish individually?
How do you plan to heat each of those containers appropriately?
How big and how many grow out tanks do you have?
Live plants? IAL?
What foods do you have prepared to feed the fry, do you know when and how much of the food, and how to keep the food alive?
Heaters, sponge filters, lights?
Do you have the hours per day it takes to do water changes in all the individual containers, every single day? Not to mention the regular water changes in the larger tanks?
How exactly are you going to go about selling these fish? How are you going to sell fish that people rather not spend the shipping costs for a pet store colored/quality VT? How are you going to sell them?
Know how to ship them and how to go about getting supplies to ship them? During winter since it's coming up?
Do you know how long it takes from conception until they are ready to be sold and do you have months to spend on one spawn?
Just some questions to ask as it seems you may need to do a bit more research if you think you can pull the male out during spawning - they are cuddled together under the nest and the male is the one that needs to care for the eggs to prevent fungus...
