I prefer plakats with thicker bodies and a bit of a dipped head...I'm not a fan of plakats with long bodies...just look weird. As long as the trait isn't extreme it shouldn't affect much as far as health.
Who am I? Well I am a Junior Member of the International Betta Congress and a breeder of white HMPKs, red dragon HMPKs, black/red dragon HMPKs, metallic multi HMPKs, blue masked HMPKs, and now multi color HMs. Soon to add black HMs. I will be showing in New Breeder class in fall of 2012.
