Sounds like I have a mover on my hands - I've had him for about 4 months now and he's done this the whole time. I enjoy it! Adds life to the tank for sure.my albino sen swam laps for the 1st couple days but doesn't do laps anymore but he swims with his reflection on the side constantly and if he isn't doing it my ropefish or teug are. My gold dust never did, neither does my ornate and my regular sen "Damn It" doesn't but he has his own quirks I agree with Hendre he will settle down a little but in my opinion he will stay a mover and shaker
