^ Hate to break it to you, but 2 MBU's will definitely not work in a 120G for long... especially when you consider just one MBU needs at least 800+ Gallons...

With that all said and done, i'm guessing / hoping you have plans for an upgrade pretty soon, otherwise your puffers are going to suffer in the long run with each MBU reaching a potential 36" when fully grown...

Thanks for the heads up. I'm aware of what their future holds.
