weird shrimp behavior
Just noticed today one of the cherry shrimp are behaving oddly. He's juvie size and constantly arching his back and quickly straightening at times, using his body to spring around. A lot of times, it appears he is falling over and doing it on his back as well. Only one shrimp I've noticed exhibiting this behavior currently. Not sure if anyone else has noticed this before or has any idea what might be causing it. Shrimp around him are acting normally.
Any feedback would be welcome. Ammonia/nitrites are 0, nitrates are at around 5ppm. Temp is maintained around 78F.
