Adele, flabellata tends to grow to a fairly good size (10"-12" tall and the same wide. Take this into consideration depending on how large your terrarium is.Also, Tillandsias depend on air circulation for optimum health, something lacking in terrariums. But where would we be if we never experimented? Smaller Tillandsias such as bulbosa, punctulata, filifolia or butzii would make good alternative choices. If you have the room though, by all means try flabellata.

Thanks Gonzer, Froggie terrariums can sometimes fet a little stagnant but snakes need good airflow too so it should be alright. I'd hate to kill the pretty little thing, but I'll toss it in there! The instructions say to water into the crown and never let it dry out. Should I take it that a little puddle of water in the crown is good all the time? -or to let the crown dry out and not let the medium dry out? It's in a fine bark chip and sphagnum mix with it's own little moss colony growing on top and looks like it's thriving...hope to keep it that way!!

Mine don't always have water in their cups but yes, don't let the soil go dry. Just don't keep his feet soaking in water for long periods of time. They're a hardy species, can take a little neglect here and there, and are generally plain easy! Throw a photo this way sometimewhen you're finished!

Decided after all that it would be too tall for the small terrarium so it's in the bottom of the big one. This photo will show you my terrarium which houses my 3 adult snakes and about 5 plants. I shouldn't have too much trouble keeping it moist but I'll take it out when I go on holidays just in case. Cheers, Adèle
