GOOD LORD!!! I was just trying to ask a simple question!!!!! First of all, I know that I am RESPONSIBLE for my actions and what goes on in the tank. I AM researching by ASKING for others opinions...Anyway, no, there are not ANY in the tank as of yet. I learned my lesson the hard way having three yellow or red or whatever you want to call them in the same tank. I will only add two, so as not to cause problems in the future. Thank you very much for your advice, opinions, critiques or whatever. I really didn't think this needed to turn into a huge debate. Sorry if I sound grouchy, but I think that some people's answers (Dogstar's) were a little condescending. I am not totally new to the hobby, but I DO still have questions, and I just wanted some advice. Anyway, thanks. If I actually do get two purple firefish, I will let everyone know how it goes.
