sounds to me like your fish are really stressed, check water params first, and how bright are your lights btw?

what kind of Piranhas are they bro? They may just be really stressed out.

What size are they? What size tank are they in? Which Piranha species is it? There could be a couple of different things that would cause them to darken.
