I'm setting up a new tank 120cm(L)X70cm(D)X80cm(H) which is quite high and deep. I know your WRGB 2 Pro 120cm will do well for this tank, but I'm curious whether a tank this size would also be suited for 2 x VIVD 3s or if that would be too overpowered or crowded. If you could share how multiples of the VIVD 3 work with different tank sizes, I think that would be helpful in making the best choice.
