It's really difficult to get a good measurement in their jar so they take them out of the water and measure them. It's really not that bad....seeing how bettas can live out of water for up to 5 hours.
There's another reason:
Let's say I have a female betta that's a little less than two inches long...I need to have a male around 2-2.5 inches long to be able to breed her...I wouldn't know his size and then I'd be dissapointed when I get him out of the box because he's not fit to breed with her.
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.
