That is a beautiful fish! :D
With the exception of one CT, all my female bettas are VT.
Without exception, I keep bettas for their 'personality' rather than a specific color or finnage.
If the betta is healthy enough to engage in her surroundings and shows interest in me and/or the fish surrounding her, I'll give her chance.
My first betta, Baby Blue, is a VT. She's over a year old and despite one injury which deformed her top line (terra cotta pot drainage hole) and an illness (popeye) that has left her blind in one eye, she has grown into a well colored and well-finned beauty. If she was in her original state (flawless), she'd be lovely to show.
Her ultra-aggressive tendencies would make me think twice about breeding her.
Here's some questions that only a breeder can answer: When you think about breeding a pair, are you only considering physical characteristics, or does a betta's 'demeanor' get considered as well? Does a healthy betta worthy of breeding need to be somewhat aggressive, in order to be interested in breeding? Is aggression linked to their intellegence as well? (more aggressive, curious bettas survive than 'nice' bettas? Are any behavioral traits linked to any other quality you'd breed for?
