Hey! I'm new to arowanas and i just got him today. I have him in a 10 gallon tank as of right now, until the 55 gallon is cycled. Hes very small, Maybe about 7 cm. I've had him in there for 8 hours, is it normal for him to kinda dwell at the bottom of the tank by the gravel? Or is it something I should be worrying about? Is it because hes new to the environment?
