Green chromis in a 2.5 gallon

No. It's too small. For pico tanks like that I would only put in an invert or two and some easy care corals.
 
To small for that fish they get to a decent size. A tank that size they sell small gobies you can have in there..
 
Personally, I wouldn't put one in anything smaller then like a 29 gallon biocube. They do get kind of big. Maybe 1 in a 10 gallon short term
