Heard a big BAANG in the middle of the night, turned the aquarium lights on and saw my TSN swimming on his side in circles 15 min after that he joined the stars Man, I just had him for like 1 ½ month =/ He prolly smashed into the aquarium walls.
MY TSN was kinda nocturnal, was resting during daylight and when lights out he came out from his "hiding place" I've allready called my LFS to get a new one for me, and they told me they would have one in a week at least thats good news
