"bettas can make a profit??!!" yes... And no. I learned to listen, ask, watch and study. I listened to the people in my area, listened to how and when to ship (if I were to), I asked for what people wanted and did not want, watched how info was given out by others, and studied tail types more. I found... People enjoy LEARNING but never CRITICISM. Saying "your a bad fish owner" VS "Bettas are actually tropical, and would live longer, healthier, with a heater set to 78-80. If a heater cannot be provided, try to keep the temperature from dropping below 76." I'd rather be informed them hollered at ;) also I found veils 1/5 liked, dumbos 1/5 knew about, 3/5 wanted crowns and 4/5 wanted half moons. I started to get all my stuff years ago so I had only an 8.00 fee for previous spawns and the most my next spawns were goin to cost was the cost of new breeders.
On that note ask around your area, especially if deciding to deal with veils. Ask them WHAT they want to see in a "perfect" veil. Pointy caudal? Long? Narrow? Wide? Also integrate dominant colors and patterns like (here people love them) Dalmatian and butterfly :)
Yes, I have thought this through

I would like to get a line of veiltail going, but I would need to do what I stated above. Plus I no longer have extra tanks, just three... One holding an irridescent blue female from my last spawn (CT/VT resulting in a Shag Veil as I call it lol) and a multi colored female crown (tank divided) and the other holds a pet veil who is just an immitation Cambodian. :/ this last month was not kind to me and my "breeding colony" and plans.
Edit: for me a veiltail would had a decent caudal spread, that is Ben on both sides, meeting together at an even point, the anal would not be super long, and the dorsal would be wider without curled spikes. :) but, that's my idea lol.
