What kind of puffers do you have? It's just that some puffers I've seen are
very aggressive and will anything you add to their tank.

Matt,

That film on the water surface is probably protein. Since you have a
brackish
water setup a good solution would be to add a couple of black mollies.
They eat
the protein and will clear the surface.

Good luck.
