I made the decision yesterday to not go back in to fighter breeding. Heres my advice for crowntail females.
Get yourself a good looking female, veiltail is fine. Get yourself a really strong looking male crown tail - good strong forked tail!
Spawn them, get rid of all the resulting males - too much rubbish on the market, don't put any more out there. Keep half a dozen of the best females (you will need to wait until they are about 4 months old, often the best finnage are the slowest fish to develop. Cross the top 2 females back to their father. Keep the best half dozen females, ditch the males. This time find another high quality male and put the females to him. Resulting females should come out like this
These are second generation females
and males
Cross once more and you will some nice looking males and females
