The fry are doing ok. Last week I got sick and could barely get out of bed long enough to feed them much less for water changes. Thank goodness my husband knows how to do it but he works so he was to tired to do as much as I do. He was only doing daily 25% changes when I do 50-75% and 100% at least once a week so when I got better I noticed that a couple of the largest fry had dark edges on their tails which looked like fin rot. I'm back to my regular cleaning now and it is going away. I also have a few fry that have white specks on their tails and I'm worried that this may not be normal, I don't know what to do if it isn't and I'm worried that whatever it is could spread to the other fry :(
I also had to separate the runts out into a 5 gal because they were constantly having to hide and couldn't eat. I thought there were 4-5 runts but it turned out there were 14. There were 15 but one got eaten while I was trying to net it. They are doing great now and have almost doubled in size in just a few days.
Some of the larger fry are getting pretty aggressive, especially when I'm feeding them. I feel like a couple have passed the playing stage but I keep telling myself I need to leave them in as long as possible.
Here are 2 video's from a few days ago right after I felt well enough to get out of bed. The 2nd one is of one flaring and chasing the others. IMO the cutest thing in the world is seeing an inch long baby betta flaring
