I'm moving and need to find a place to put my fish tank. The best location seems to be next to a radiator, although I'm, not sure if that is a bad idea...
The tank would be above the height of the radiator, not like right on the floor next to it, but next to it none the less.
Cast-iron radiators are designed to sink heat into material.
The tank might raise to a temperature that will be unhealthy for the fish.
Keep an eye on the temp.
Hopefully there is another location?
