I just put my betta in a new tank today after acclimatizing him. He kinda just checked everything out at first, then later in the day whenever I was in the room he'd be pacing the very front of the tank non-stop. I don't think he could be bored since he only just moved there and he's got lots to look at. It's a 5 gallon tank, much bigger than his last or anything he's been in previously. Could it be that he's just swimming lots cause he's enjoying the extra space? He'll still kinda swim around to the other places in the tank but he didn't have this particular behaviour before. Just curious what everyone thinks!
