Pacific Chorus Frog enclosure and feeding questions

[Andie]

Hi Everone. Last Spring, for the first time, I constructed a water feature in my back yard. Much to my surprise, on April 1 and again on April 7 Pacific Chorus Frogs laid eggs. 100s of them. As the tadpoles grew I could see that they needed a larger enclosure, so we bought them a 5' hard plastic kiddy pool and there they grew and grew and morphed and all left the "pond" by mid-September. I watched them all summer long and as I would sit there enjoying their company, adult frogs would come for a dip in my "pond". When the last of the froglets had gone for good, we emptied the pond. I'm thinking of doing the same again this year-- if the frogs will cooperate. But this year, I'm thinking of keeping some of the last froglets to morph as pets. I would like to set-up their vivarium within the next couple of months so it will be ready when they are. After trolling the Frog Forum and other boards for info I have a fairly good idea of what it will take... but I do have some uncertainties and questions.

To fit the available space in my home, I've pretty much decided on an Exo Terra 24 x 18 x 24 with a John Clare-style hydroton false bottom to provide biological filtration for a water feature. I know from experience they will like some water. Paul Rust also recommends it in his PCF care sheet. Not quite sure how to provide access to the pump with this set-up. Any ideas? Also, how many PCFs would be happy in this size enclosure?

My vertical space is limited and to accomodate the 24" tall enclosure, I have found a couple of very low profile lighting fixtures. One is a sleek T5HO fixture here: Odyssea T5 Aquarium Lighting Not looking for a tropical set-up, so is T5HO overkill? The other is a sleek, energy efficient LED fixture... LED Freshwater Bright Will the LEDs provide enough light for moss and plants? I would really like to go with LEDs if they would be suitable in this situation. Do PCFs have any special lighting requirements?

And thinking about a primary food source for my captive PCFs... Are petstore crickets with gutloading and dusting the only good option? It seems as if the soldierfly grub is nutritionally superior without having to gutload or dust? I haven't been able to find the nutritional analysis on silkworms-- how do they compare?

Any guidace would be greatly appreciated before I take the plunge and order the enclosure & lighting!!! :-)
