[PDDM]

K Heres What You need to know:
1)Im only 14
2)I Have 2 Tanks,A Ten Gallon and A 26 flatback which has the dimensions of:30inx12inx16in
3)The crested Can Be Breeder Bought for 85$
4)The Fire salamander Would Have to be store bought at 89.99$ and thats without tax
5)My Leo is curently living In The 26 gal,Id probably move Her to The Ten Gal and Put the crested in the 26 gal,If I Got the salamander I Would Put it In The ten gal and leave my leo in her Big Tank
Info:
Now Im stuck...I Want A Crested Gecko,But Im Also looking into the idea of getting a fire salamander,I can only get One,I Know a breeder In The area That can Sell me 1 for 85$,whereas the Fire salamander will be bought From A Pet Store And Will Cost 89.99$ Plus Tax...Any Suggestions?Has anyone here Dealed With Salamanders and cresties???Also if anyone can Name any Pros On Cresties Thatd Be Great...Oh One last thing,About The big tank Its 30x12x16,If i got the crestie Would it be better to Turn the tank On Its Side Making It Really tall?If its absolutely Nescesary Id Guess Id Do that...
