Uhhhh, 2.5 into a SW tank. Not such a wise idea if you don't got every single time on your hand to maintain it. Other than that, great! Cherry shrimp are nice for a 2.5. But personally if I was to stock that tank, I'd get me 2 dwarf puffer. So small, you wouldn't believe it. They get up to a maximum of 1" but they will try and eat snails of their size and pluck away on those shrimps also. REAL mini ]\/[onsters if you ask me.
