12 days old, have been power growing them, feeding about 4 to 5 feeds a day making sure everything is eaten before another feed. Always making sure they're nice and round on the belly. Have seen roughly about 5 die off due to not being able to eat bbs. Culling will start by the start of week 2, some of them being half the size of the bigger ones.
I woke up yesterday with my fry having velvet all over them. I treated the problem straight away with a 50% water change. Increased the temp to 86F/30C, threw in 2 Indian almond leaves and about a teaspoon of salt for my 50% water change. After waiting 24hrs my fry are back to normal and fighting each other again.
