Aww man, those fry are so cute ^^, I never saw baby betta's before! I love your journal, I've read every page yesterday/today, great job on the tank for kaon. I'll definitely be following this as your fry grow.
Kaon tends to be chronically ill. I had to take him out of the tank to treat yet again. so after a while, I put another male betta in. He's not had a problem. Kapn has had issue in every body of water, including unmedicated, clean-changed daily water.
Three sisters in a tank that should be thrown out eventually.
Sorry to hear about your loss. Fish have always held a close spot in my heart as well. I just recently lost a figure eight puffer that I have had for almost 2 years. He had such personality too. I would feed him by hand almost every night too. I would put the food in the palm of my hand and lower it in and he would sit cupped in my hand eating. Not sure what killed him, I think old age as for the last few months he was acting rather ill and not like himself and I could not figure it out for the life of me.
As for your tank I love it. I wanted to do something similar but something always seems to come up right when I am about to start. I was going to make a betta cave where only a little bit of light would be coming through to make little ribbons of light in the water,,,,, cant seem to get started though.
