To many to add?

hello all...well i just say a court jester goby at my lfs, and well ive been waiting months for them to get it...i just dont know if i am starting to over stock my tank...most of the fish i have are small (the wrasse is growing a bit..but still around 2.5 inches) well...also if it is not overstocked already would the the firefish mess with it...i know its not really a goby but a dartfish...but idk...thanks

ugh..ok nvm thats not my fish...in that pic there is one black spot on the tail but for mine it has another black stop on the end of the dorsal fin...ugh WHAT IS THIS FISH!!! also no black on mines tail...ugh...well eventually ill bring it to a larger tank anyway lol...

 

ugh...i have to decide quick! i wont be able to go this weekend or tomarrow got get it lol...and by then it might already be to late! i have been waiting like 4 months...and now i can decide if i have too many fish! ahhhh
