No picture of the dam. Dam was bred by Sieg Illig, and was a turquoise blue female DT. She had a bumpy topline, but full and even lobes with a slight bump on the peduncle. She carried grizzle.
I wasn't sure what to expect with this backcross. I definitely expected both STs and DTs to pop up, since the foundation male obviously carried DT. I was hoping that the impressive qualities of the male would override the qualities of the female, and be doubled up in the offspring. I crossed my fingers and gave it a shot...
The tribanded CT female on the left was a complete and wonderful surprise! I did not anticipate the nearly perfect division of the colors on the unpaired fins, or the beautifully smooth topline, or the full ventrals, even anal, and full dorsal! Points of improvement are to thicken up the caudal peduncle (hopefully with the help of more DT) and to straighten the outer rays on the caudal.
This female later on gained more male-length finnage that I would have liked. I have seen a lot of older CT females gain male-like finnage, and also be prone to egg-binding. Fortunately for me, my females seem to know what to do if they are becoming egg-bound...they build their own nests and lay their eggs in it!!
