I bought the exhaust fan from sim lim tower ( actually meant for computer stuff) to churn out the heat from my tank cabinet as all the devices are inside the cabinet and this can be rather hot
And stray voltage won't actually electrocute fishes. there is no path for current to flow through the fish to the ground.
When u put your hand in, it's a different matter coz now current can flow thru you to the ground, then you will feel the shock.
