Back in 2015, I introduced 'Zig-Zag', a deformed Betta brownorum juvenile from an F0 x F1 spawning. As a fry, his spine was so crooked I thought he would die as I couldn't see how his internal organs could function. However, not only did Zig-Zag survive, he thrived. More surprisingly, was that over time his spine has straightened, leaving only a slight indentation in front of his dorsal fin as you can see below.
Sadly, having lost his spawn sibling quite recently, Zig-Zag is now the only fish in my fish room descended from my previous Betta brownorum pair. What's more of a shame is the fact that my current pair don't seem to be throwing that characteristic lateral blotch on any of their offspring.
Hailing from Melbourne, Australia, I currently keep and breed a number of species from the coccina complex.
