Thanks Geert. But the spawn was small, about 70 fries only. Guess the male may have been a little overweight to do a proper job. Male was AAA Thai, oya, Matsuyama line. Female nisai Thai showclass, unknown line. Because the spawn was too small, I fell it too early to judge this pairing, so I will try again next year, if not split the pair.

Because I study abroad, my dad told me not to buy new stock until I finish my uni in about 2-3 years more. Plus I am a student, my budget very tight. And also it is hard to find TVRs sold here at the moment. If not, I would love to work with Oishi, Kashino, Mita and Fukami ranchus. But since I cannot do that, I will have to improve my line using what I have in the time I have...call it a learning process. Of the 11 BBRs here, I find actually 3 to 4 of them quite all right. Their tails are not weak actually. The rest maybe, but I keep them for observation on their development. That is how I learn.

As to body length, to my knowledge, ideal is as Pat suggested with the circles or ratio of 1 to 2.5, but it really boils down to individual fish and preference. Also I have seen some winners in JApan with short bodies as well.
