dear wibowo,
to tell you the truth, i was surprised that now local showa has the similiar trait as Japanese, i've bought few local showa from the past 2 years, most of them have a defined sumi (in other word, sumi is there even when the koi is still very very young---a.k.a lousy quality)...but your koi has the 'tategoi sumi like' especially on her mouth part !!!
anyway, i din go back to Indonesia last week due to exams...and my bekko managed 4th (46-50xm)...haha...now it seems that his 'male' body shape unable to compete with those female koi in term of body shape...sign of retirement from show and shall let him enjoy free world now !
anyway, i talked to my dad, and he agreed to TOTALLY renovate my mud pond and hopefully an extension, n i think he caught on koi fever (finally, after goin there last week)...so, i'll be back next month, if you want to 'titip' some of your koi, it is my utmost pleasure boss ! for the detailed info about pond size depth, my current feeding regime just 'japri' me
Rgds,
Dimas
