Hey everybody, so I got this PJ cardinalfish from my LFS a couple days ago. It was at the store for a couple weeks and looked healthy, ate well, etc. Just this morning I noticed his spots are faded on one side and it looks like he has a big white bump. I'm not sure what/if anything is wrong, any help is greatly appreciated!
This is my first fish in my 28g nanocube.
Parameters are:
Ammonia: 0
Nitrate: 10ppm
Phosphate: <0.05ppm
Alk: 10.9
Ca: 450
Mg: 1320
