About 2 days after I add the tang to my new tank it hangs out in the corner and swims up and down like it trying to swim out of the tank and that spot is the exit???
its 40 gal he move from a smaller tank only got some 2 clowns and clown gobies and looks like he settled down today I added some dark time to my lighting schuel I had the moon lights on all night
I've heard of them doing this, it's not used to being in a tank yet, He's used to being able to swim as far as he wanted. And he's also probably stressed. Give it time, and find it a bigger home, 40 gallons is way to small.
