Hi Guys,

Have rather unusual problem. I experience fry loses within about 2 hrs from BBS feeding.
This does apply to fry about 3-4 weeks old.
In other tank with younger fry no loses. Water is good quality, and we are talking about fry from the same pair.

Some time after feeding fry start panic and whirling the few of them die sitting on the bottom. I really narrowed it down to the fact of feeding. BBS is fresh, well strained (no unhatched eggs) and rinsed.

Have you ever experienced something similar?

Thanks
