i can t believe Brian advise you to buy a banana girl!!!! First as say frosty don t breed a normal male except if he has really odd pattern or color (dinker).

Second if you want to start breeding you need to identify your hachlings targets. what do you like. For me banana is a poor morph that age badly , just very high hands combos are great and out of your budget ( banana pied, banana clown...) with exceptions of enchi banana and cinny/black pastel banana combos.

third always buy females first as they need 3 years average to get ready while male just needs 6month to 1 year.

So i will advice few morphs that you could check on for pictures and no something that i have in stock and want to sell you:

Enchi
Fire
Lesser/butter
mojave
orange dream
leopard

but if you have those 600$ to put on a single animal then you can go :
recessive genes:
desert ghost
clown
lavender albino
ultramel

co dom and dom combos:
firefly enchi
bumblebee enchi
lesser leopard
mojave leopard
orange dream fire
orange dream Yellow belly
dreambee
crystal
firefly spotnose
superpastel enchi
