My betta that I've have for about 2 months just got put into his new cycled 10 gallon aquarium and won't stop glass surfing! He was in a 5 gallon before and he rarely ever did it and I also never had any backgrounds for the tank. He was put in the 10 gallon about a week ago and whenever I walk into my bedroom he is usually darting across the front or the side of the tank. I put a black background on the back side and one side of the tank where he is always swimming... I have a few small crypts, 5 or 6 dwarf sags in the tank as well as two anubius'. I also have a pretty big piece of driftwood and two other decorations to fill the tank. He is very healthy and eats fine but I don't know what to do about the glass surfing?? Is there anything I can do or should I just leave him be?
