What fish to get next?

[pokdbz]

I need some help picking out my next fish. I have it narrowed down to 3. I have a 29g with 1 B&W perc and 1 regular perc. Here are my choices that I would like to put in next. Which one do you think?
Citron Goby
Firefish Goby
Purple Firefish Goby

I'd go with the purple as well.

Sorry to change the opinion....
But i would get a firefish goby.
All what matters is what color from red or purple do you like better?
Then you`ll get your answer.
Good Luck!!
