Okay, I would watch out for the betta that used to share the tank with the red CT. Pop eye is a symptom of parasites/bacterial infection and it is contagious.
Oh no! I'm sorry to hear that. I would either lower the water level or use plastic paper clips to attach an extra piece of craft mesh to the divider. Good luck, I hope he gets better soon. ^.^
i posted on the thread ;p they are healthy and happy, although some people mistaken "there ready to breed" only, not all the time. i think of it as a sign of gratitude and they appreciate your care (imo)
