Does the color, or how much light is going into the tank effect the piranahs in any way? I heard it does but im just asking to make sure and try to make the little guys happy, im new to this... much thanks to people who are willing to help me out
In general, bright lights will make your piranhas slightly more skittish. Although they probably will not have any negative effect on the health of the piranha, they will probably be more enjoyable if they are made more comfortable.
Some say that they can eventually get used to the light, but I prefer a slightly darker tank anyways.
As for the color, I would suggest regular white lighting. I'm not sure how colored lighting would effect them but I like to keep it as natural as possible.
