Morning Lads.
Generally, when females are ready to spawn, their stomaches turn a creamy white and they lose alot of their colour and turn very dark (most likely due to the stress of defending a territory)
watch for Lip locking, tail slapping, and shivering (she should be the first to start)
As for their colours being the best they'll show ;-) Its true for pretty much everything except severums lol. Most of them look very dark, and that little white patch is the best your going to get ;-)
Also, Turqoise severum - Green Severum - Gold severum - Red severum = all the same fish (as long as were not talking wild caughts, then theres plenty of debate) so interbreeding isn't really an issue. (Sort of like breeding mongrel dogs - No offence ment, but commercially bred severums are exactly that. A fish thats been bred from numerous species/sub speices over many generations)
