    Anyone else notice fish in captivity, excluding ornamental fish like B.splendes and goldfish, have much less impressive finnage as opposed to those in the wild? For my it's my Betta pugnax. The huge male in my tank has only a hint of tapering and a slight tinge of blue. But the ones i see in the wild are only 70% his size but have much MUCH more vibrant fins... Could it be the lack of females to entice him? or perhaps hormones that remain in the water...

    why I don't do garden hybrids and aquarium strains: natural species is a history of Nature, while hybrids are just the whims of Man.

    My tank's right up against the window... enough light for the plants to live on considering it's a 6ft with only 75 watt FL

    Stronger competition for females? Female preference for pretty finnages?? Much larger volume of water?

    Hence the weirdness of mine... he doesn't fight and yet has short, almost female looking fins. But the sports/bars/laddering(proper term?) on the fin and green colouration on the gill covers suggests it's a HE
