I have had a few die here and there from getting picked on, but I have lost a couple now and I can't figure out what's going on. I have one right now that i pulled out that's swimming funny sometimes like a swim bladder issue. I did a water change last night, but I haven't checked the parameters as I noticed this one before I left for work but haven't had the time to do that yet. I'm only losing Cichla, not the other fish I have in the tank (a couple catfish and a bichir). I should have been trying to figure this out already, but I always wait until it's too late thinking it's just a fluke. I took a video, but I'm not sure how to post it. Maybe I'll upload it to my youtube account and link it.
