I bought a Pearl Gourami on Thursday, it was shy at first but soon started swimming around exploring. Today however it is at the front of the tank swimming up and down the glass, and from left to right. I thought it might be hungry as it didnt eat on the first day so I put some food in but it barely touched it, it only nibbled on some of the smaller pieces.

Is this normal behavior? Or will it settle down? My ammonia/nitrite levels are good so ive ruled that out.
