Will try to keep this short... DH has a massive 400l fish tank that sits on top of a metal cabinet...the tank is not secure to the cabinet it just is placed on top. He is adamant it wouldn't fall over...we have a DC 2 who is climbing pulling everything and tonight he pulled the TV on top of him while I was in the room. He is fine but it happened so quickly I am in shock. I've asked DH to get rid of the tank as I think it's an unnecessary hazard that I don't think is worth the risk. All I am getting is sarcastic replies of how I'll have to get rid of my hair straightener incase he burns himself etc. AIBU for wanting the tank gone it's so heavy 6ftx6ft
