Yup, those bad boys are TTs. Got them from Howard (where the hell is that guy?) when he was still breeding them.
I'm just lurking your threads bro! No more TTs for me. I sold and traded them all off. I had them for 2 years and needed to try something new! TTs are pretty much bullet proof though. Easy shrimps to breed cause they are a wild strain. Glad to see that they are still going strong in your tank Nick.
