The first blue is second generation, a strike of good luck, as we have only had the tank a year & a half and no real birth control method. :-? Unfortunately most of the other fry he came with had a lot of yellow and were given away.
We are novices learning as we progress, many mixed colours (motley crew).
The black delta was care of LFS, and has some young coming through. Hope to progess further with blues.
shiuh - Great to see another Architecture Student out there in the fish world.
