I have a 8-9 inch Livingstoni in my 125 gallon. He is normal when the tank lights are on, but as soon as the lights go off, and have been off for a while, he seems to go crazy. He claims half of the tank and attempts to mate with either a male aulonocara, a male iceberg fryeri, or a female kenyi. He also likes to try and fight with a pleco thats just a bit bigger than he is. And yesterday night, I witnessed him successfully spawn with the female Kenyi, and shes holding eggs now. He acts completely normal during the day, is he just being a weirdo fish or what?
