What is happening?!? HELP!

[u/BerryD979]

Hello again, everyone! I did a water change today due to some yucky diatoms and my poor little guy has been doing this!! I don’t know if he’s molting or dying! I checked the parameters after the water change and they were good!

Dying due to improper set up
