Well, I've had my fish Persica since the summer... He's been the best companion to me in the dorm... And recently he built the best bubble nest ever.. I was so happy.. I've spent the last hour crying. I'm pretty sure he's going to die. :(
For awhile, he's been laying at the bottom of his tank, and at first I thought he was sleeping. Then I realized he hadn't moved for a whole day, so I tried moving his tank to get him to swim. He wouldn't, so I just lightly touched his fin. He reacted, but he can't swim straight. He just sort of flops, and when he does swim, he just falls back down on one side or upside down... Now he's breathing heavily... VERY heavily.. What have I done wrong? I haven't done as many water changes as I should lately but I checked his water quality just two days ago and it was fine. I'll check it again now.
