im wondering why my 3 phantasticus seem to only be halfway to adult size. they've all been very healthy from day one, but i read in neil's old article in reptiles magazine that they can even reach full adult size in about 12 months. they've always had UV light and have never had problems feeding. they're still perfectly healthy, but could i be doing something wrong, preventing them from growing more? the 3 of them are house together in a 15 gal, heavily planted. ideas?
