First off, forgive me if this is in the wrong place. I am new to these types of things.

Okay, now for my question:

At the fish store, I was looking to by a few blue-green chromises to add with the other blue green chromises to make a well rounded group (from 3 fish to 6 fish), yet there was only one there. Now in the tank with him, (I'll assume it's a he), was fish labeled as a "yellow-tailed chromis". Since they were not fighting, but instead interacting as friends, I thought I should get him and another in the tank above to "substitute" for the blue green chromises. The worker said that they should be fine together, as she has a few. After I went home and started acclimation procedures, I went on-line to find more info. Sadly, there was none, since the fish were actually "yellow-fin chromises". I couldn't find much more then there scientific name, which I found on fishbase.com. If anyone has more info (i.e. temperment), or has experience keeping them, I would be gracious to be privy to one's knowledge.

Thank you and have a great day/night.

P.S. Sorry for the post being so long. I was taught in school to be excessively elaborate.
