DQ: Dead snails is the worst smell... EVER. Gah luckily mine don't die often DX
That chart is good but can be misleading. My B1 spawn is six weeks and the largest ones are bigger than the chart shows. If you can tell he's a male, he's probably stunted. Lots of clean water and food will get him to grow over the next month to full size.
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.
