new cresties

[procman]

hi there,new crestie owner with a few question's.I just purchased a collection of crested gecko's.Don't know what sex they are yet.I got 6@9 months old,3@6 month's old and 3 @3 month's old.Came with 12 10 gallon tank's.I intend to make some melamite glass fronted display case's with live plant's branch's maybe some kind of misting system.would 18x18x36high be big enough for 3 cresties in one case???Any ideas on type of plant's e.t.c???Also i keep reading that they love fruit baby food -they won't touch it.Tried peach, apricot, banana.tried the t-rex gecko food, nope to any of it.Tried this for about 4 day's(changing it daily)Then tried cricket's, thankfully they ate them.I'm worried that if i can't keeep a steady supply of cricket's at home they will starve even if i put other food out for them.Any suggestion's as to what else to offer them???At the moment i'm feeding them 3 appropriate sized, dusted cricket's every night and misting them 3 time's a day.Is this enough cricket's???Had them 2 week's now,got paper towel on floor of tank's. strip's of egg carton's,screen lid's.Room temp 65 f to 70 f.I wanted a hobby for home and this opportunity came up.Hope any one can help.sorry about the long winded letter i won't bore you again.Promise!!
