Genetic defect?

My trio (2F albino &1M cw26) breeds about every two weeks. Until today, I have 6-7 spawns. I feed my fries with microworm only for the first 2 weeks. I switch to crashed flakes after the first two weeks. Recently, I found out my fries from later spawn are having a common problem. Some fish rear body (tail) are having a "little twist". I would like to know is this twist a signal of genetic defection?

If the fry from the other spawns are ok, then I would rule out genetic defect, but look at other things. I would look at waterqulaity and such things. You say you have changed food for the fry. This might be worth an experiment too.
I always cull deformed fry. The only fry that comes out of my fishroom is the ones that are ok.

I had a problem with some of my Brochis splendens fry last year, where after about 30-40 days several fry developed twisted spines or clamped, under-developed caudal fins. With my fish I suspect lack of food during development may have been the problem- I believe I grossly underestimated how much food they can eat during development.
