Joist direction

[ballyclover]

am buying a new fish tank, total weight when full is almost 1/2 ton.

In order for the support to be there the tank will be hard up against the wall which between my home and my neighbour (semi detached) problem is I can't take up the floor and check as we paid a fortune to have laminate flooring down and I don't want to ruin it. I am hoping the beams will run outwards from the connecting wall. Is there another way to tell? I obviously need to spread that weigh over as many beams as possible.

Thank you

They will very likely run in the same direction, as they do on the floor above, and also your neighbours.

(Assuming this is the ground floor) can you get under the floor - there is usually a crawl space.
