I have always used GE clear silicone sealer to hold coral together in
sal****er tanks. I don't think super glue will last long under water
especially on ceramic. Allow extra time for curing before putting it
back in tank. Silicone caulk gives off ammonia while curing.

Broke an ornament cleaning my tank. Normally I would fix something
like
this with super glue. Is that OK to use in a freshwater goldfish
tank?

Thanks,
