Glad to hear of another serious Hydrosaurus keeper!
These are 100% pustulatus. My male is a John Steele line animal. I've had him for about five years. My female is the offspring of wild caught animals from Anthony Sainz, back in the day. She's getting up in years now but she is still a great breeder. I've had her for almost seven years, and she was almost six when I got her from Anthony. So her genetics are extremely precious, seeing as how she's unrelated to any other pustulatus being bred in captivity.
I have another line as well, but they aren't old enough to breed yet.
I just posted these to morphmarket as well, yes.
I have five available, which will probably be my only ones available this year. If you are serious about breeding them, I'll give you a discount. Especially if you want 4 of them. I'm highly motivated to see this species be bred in more collections.
Where are you located? Would you be paying all at once, or do you need a payment plan? I'm fine either way, but as the season gets colder it might cause big delays in shipping windows so just be aware if they are on a payment plan there's the potential to not ship until spring.
Also, if you have an email you'd like pictures of the babies and parents I'm happy to do that. I tried to upload them here but the website said the files were too big, and I'm not techy enough to know how to fix that.
