240 gallon floor reinforcement

[Fishkeepah4]

I have a 240 gallon 8' wide tank I am setting on an exterior wall. The joists are 6x4 @ 32" OC. The subfloor is 1" thick. Would this be something needing reinforcement even with this setup? It has 4x4s on every joists going to the stem wall on the exterior wall. (And then every 6' on from that).

Not sure this is the place to be asking that. You want to look into asking a structural engineer a question like this.

I agree with @DocRose best bet would ask a structural engineer.
