Hi, I just had my first fish death in my 60L. I've had 6 otos and 13 pygmy corys (+ shrimp) for a few months at this point so I thought I was in the clear, but just 10-15 mins ago noticed one of them flapping around near the surface with a very brown patchy belly. I immediately netted it out to see if I could help but it died shortly after.

Making a post (pictures attached) to ask if anyone knows what this might be, gut blockage, disease, etc? And if I should take any precautions for the remaining otos or the pygmy cories (all 5 oto bellies look fine at the moment).

params:

0 chlorine

0 nitrate, 0 nitrite, 0.25 ammonia (I'm working on it..)

150GH, 180KH

8.0 pH

Thanks for any advice..
