Not much at the moment, Gangster. Just got the farmie hybrid that started it all for me. He's pushing 18", making it a real headache for me to get the other three pbass I'm growing up in there. I want them to at least be 12" before trying to introduce them (again).
And yes, the raph is pretty chill. Got her as one of the 4" Pet Supermarket critters. She does hide a lot, but you can occasionally catch her out.
