Hello! I have a pleco who has just recently started to change colors, on impulse. It is crazy. My pH and ammonia are fine, the food, temperature, and tank mates are all the same. Sometimes the pleco is a very, very light brown color. He is usually light colored when the light is off, but as soon as the light comes on, it turns back to the normal dark brownish/black color. Does he think he is a chameleon??
The skin on the pleco is still very tough, he doesn't act sick. Please help if you may have any ideas. Thanks everyone!!
