Aechmea gamosepala. This is the bromeliad on the right in the terrarium photo earlier in this album. The Imitators love it and it has a bunch of tadpoles in it. Stays pretty small and holds water. Unlike most of the commonly available terrarium bromeliads, It's not a Neoreglia, and when I bought it there was another of the same type with a narrow tall flower stalk sticking up out of the center with pink or lilac tinted flowers on the tip.
