Woke up today to find one of the small loaches dead, not just playing dead. Measured him at 2.5" nose to tail. I looked him over and couldn't find any issues. He was thick but not obese with no signs of any skinny disease or eating issues. It was one of my most colored up ones with his middle stripe rounded towards the belly. A damn shame, I really liked this one.
I tested the water and everything came out good ammonia, nitrates. I have no idea what could have happened, everyone had been feeding well and acting normal. I usually count them all when I feed.
I'm stumped on this one. The only thing I can think of is I think he's the one that likes to sleep inside a piece of driftwood away from the others and maybe got stuck? Issue with that theory is I didn't see any damage to him and I found him on the opposite end of the tank, if he had been stuck in that piece there is no way the flow would have pulled him out. Again, stumped on what may have happened.
