Agree NY is a good vendor!
I’ve had good experience with NY Aquatics as have others here.... I’m sure I will not be the only one chiming in on them.
Good to hear, as I have an order in-place with them - took advantage of their Memorial Day sale.
@Sashaka, as I know you're aware, it's almost impossible to get fish through the supply chain without some disease or other hitching a ride. Looking at the butterfly, there are two things that pop to mind; Uronema, which can be contagious, and bacterial infection, which usually isn't in good water. Some of the gram-negative bacterial infections can go from zero to sixty in well under 24 hours though, so there is a possibility that the fish looked significantly better when it left LA's packing team in CA.
