Forgive me if this is an old thread. I just did a search on letting fry flare for optimum finnage... and I found this one.
I had no idea this was necessary ... Now I do.
Thanks for sharing the wealth of your knowledge.
2. How does one exercise their fish.. and how often should this take place with JARRED fry? I would guess one would gently swirl the water and allow them to swim against the current. Is there anything else I should know?
