gourami swimming against glass

[Omega3s]

Hey guys, I just have a quick question about my powder blue dwarf gourami's behavior. Ever since I bought him, all he does is swim circles against the glass. He has switched sides occasionally but now he mainly stays to one side wall. He does this almost all the time. He does stop when the food sinks near him and he eats a few flakes so that's good. But as soon as he's done eating, its back to the glass. He is a beautiful stunning blue and there's no color loss(at least from his color at the store) im just worried about his well being. Anybody have possible ideas about what's going on with him?

a possible reason fish swim against glass is that they are uncomfortable
with their tank environment. Be it other fish stressing it out, low water quality, or lack of hiding spots. You've got to judge yourself whether something might be bothering the gourami in that tank.
