Otocinclus and Flourish Excel, bad mix..?
I purchased an Otocinclus catfish around a month ago for my sorority. Even with his appetite the algae got out of control and my substrate didn't have much in the way of fertilization so I went with flourish excel in my tank. I did the 2X treatment for 2 days (2 capfuls each day). It cleaned the algae quite well but I still had traces of it all over the pots and such. My oto was fine before treatment, I know they're finicky fish but I purchased him from a pet store where he had been living for a good long while. Yesterday when I went to do the water change I found him passed away. I know he still had food and was eating right up until the end. I also realize that Oto's are picky fish but I can't help but think the flourish may have shocked him to death. All of my girls are fine but I also think it stressed them out because a few started stress striping, and I had a sudden ick outbreak which is now cleared up. Just something to keep an eye out for. The stuff is amazing, my plants literally exploded over night using it, but I think using it for algae control does stress fish. I'm going to do an extra water change tonight and tomorrow just to try and re balance everything.
