so 3 days ago i noticed 2 of my neon's not swimming very well they had trouble going to the bottom. so i researched about it. by the time i made my plan and knew what i was gonna do they were fine! racing each other to the bottom and the top. so i thought i was just imaging it. but the next day the same problem. then it was gone... etc.
they are on a dried diet (won't eat frozen food for some reason)
the water quality is excellent though (0,0,0)
should i feed them some pea's or not feed them for a few days? should i just leave it?
whats up with my neon's ?
