I need help i have a 120g tank taht has been established for 2 year and i have a mandarin gobie but i can't figure out how to tell if it is a male or a female... Any help is helpful. If anybody has any advice on how to breed banji cardinals that would help to.

I believe that they male mandarin has the spike like dorsal fin. I could be wrong but I think that I read that somewhere. I'm sure someone else with more knowledge than me will chime in soon if I'm wrong. HTH

Yup, the first dorsal spine on the male is long, generally going back to the tail.

That was the rule I went by when I purchased mine. Either I lucked out or thats really the difference between the sexes. Oh by the way my pair spawn in my main display almost on a monthly basis.
