Wow very informative..... I hope some day you guys can crack the breeding process for the CTs..... good luck
i have heard and seen and have been asked alot by many people about theirs sexes and the way to distinguish them, even in Thailand i get asked by some keepers.
before even needing to see the fish, there is two questions to screen the basics of a male to a female; which gives around an 80% correct answer:
- is it banana gold color (male), copper red / brown color (female)
- is the body long (male) in shape or squarish (female) looking shape?
* these are the two most easy ways to distinguish them, however there are obstacles that create confusion and quarrel; such as mine is banana yellow and square looking, or its long and its copper! etc etc.
so in order to be able to distinguish them using this simple method, you have to understand how you are keeping your fish.
1- these fish's original food is live fishes, such as bettas, baby snakeheads, small frogs, crickets, small breams, etc in the wild. so feeding them or changing their food diet to dead things, prawns, or dog food looking pellets will distort their body shape. ( i never feed my fishes these things as i believe it shortens their life span and they don't need to exercise to get their food but of course your feed is more expsensive than me having to net around some ponds and find plenty of small fishes)
i have a friend who used prawns before on a CT i gave him, which was a 16 inch male, i never fed it other than live ghost shrimp and fish but after two months feeding it prawn (took a week of starving to change its habits) i got so fat it looked like a female. and this also happened to other of my friends CT's as well.
so the feed can disorientate is body shape so only its natural diet will determine its true sex.
2- so with food out of the way, its true sex can be determined with the environment it lives in.
assume you have five CT's of exactly 12inch together, with one or two females and the other males, their femaleness will stand by tending to be more agressive towards the males but more neutral towards the same sex, unless there is a size difference.
a cor das fêmeas tende a flutuar mais do que os machos, você pode ver isso quando estão assustadas ou tentando mostrar agressividade para proteger a si mesmas ou a seus filhotes, elas erguem a nadadeira superior e as escamas erguem um pouco, criando um a cor metálica semi cinza e as brânquias se estendem um pouco (semelhante ao betta siamês de combate, mas nem de longe o suficiente). somente as fêmeas fariam isso, o que se supõe ser usado para proteger seus filhotes. enquanto eu não vi homens com esse comportamento antes.
então espero que isso tenha sido útil para todos vocês e, como afirmado anteriormente, os machos tendem a ter a cor da banana, mas nas minhas experiências anteriores, mantive uma grande quantidade de tamanhos grandes em uma lagoa de concreto, e havia bastante alguns garotos gordos por perto, mesmo quando a dieta é onde cardumes inteiros de tainha pequena de água doce.
boa sorte e espero que tenha sido útil.

Amigo, muito obrigado. Foi a melhor definição do sexo dos dats que eu já vi! Levarei sempre o seu conhecimento comigo.
