arowana hiding

[Arowana King]

recently my silver is hiding behind the heater, but 75% of the other time he swims out, why is he hiding?

Does he just stop there? Maybe hes scared? Stressed? Bad water?

maybe he's cold.

Put your heater horizontal instead of vertical. Give him less places to hide to find if he's sick or not.
