Hi all,
I'm the owner of those paradisefish you've seen edited by Charles apart the albino which is not mine. To distinguish a male from a female it is not difficult, males are slimmer, have longer finnage and more colour, females don't have long fins and their bellies look fatter especially when they are full of eggs, besides, female have an esposed white papilla just behide their ventral fins, from which eggs are emitted!
At the moment I'm breeding the forth genaration, the fry are three days old and feeding greedily on infusorians which I've created. If you got questions about just ask!
