I have 4 small piranhas and one of them has some black coloring around the gills, 2 of the others are starting to get this as well...
What is it and why ?
Last water change was done about 10 days ago so im getting late but decided to ask if it was caused by something else then bad water quality.
The tank is pretty small for them but ill move them soon. 55x8x8"
The Piranhas are around 4"
