I have 1 angelfish that is showing some issues. His gill movement is rapid and it appears he is having labored breathing. Everyone else is okay. Happy, brightly colored, active, eating...the works. I tested my tank: Ammonia 0, Nitrites 0, Nitrates 5. I did my weekly 50% water change on Sunday.

Here's a video
Labored Breathing - YouTube

I'm gonna go do another 50%

Well, this angel seems to be doing better now. No more labored breathing. I'd also like to note that last night...was it last night?...either last night or the night before I gave them a cucumber to graze on. It wasn't finished but I took it out during the water change. I do believe I didn't rinse the cucumber I purchased. I'll have to rinse it a bit to make sure nothing is on it....but then again, only 1 fish was having issues......
