i have a 150 gallon tank with a large sailfin plec which is about 18" long and today he has started to turn a light brown in places, is this normal ? please let me know.
many thanks
Im definately no expert on Plecs however my Bristlenoses turn a patchy light colour when they seem a bit stressed or when they are bothered by something, sometimes they even go that colour when they are trying to compete for the cucumber I put in the tank
