Dangerous Ornaments

Hi,

I want to create a functional ornament for my arquarium which houses two
goldfish. What I want to do is glue various seashells to a plastic or metal
tube. The ornament will be placed in the corner of the tank to hide an
air-stone and air-line. My question is what material and glue can be used
that will not affect the health of the fish. I was thinking of using a 6
inch (length) plastic tube, like the the kind that plumbers would use, but I
have no idea about the glue. I want it to be non-toxic to the fish, but be
strong enough to hold the shells onto the tube base.

Has anyone attempted something like this before? Any ideas on how I should
go about making it.

I would use the hard tubing made for aquariums (the stuff used for
uplift tubes in UGFs or similar - I see it for sale in our local
aquarium store by the foot) and silicone sealant for repairing tanks.
A bigger problem might be what seashells can do to the pH of the water
in the tank. They are fine for marine tanks, of course, and for
freshwater fish that prefer hard, alkaline water; but they might cause
some issues for goldfish, depending on how big and how many they were,
and how much water is in your tank.
