Shoaling cardinals.

[Erick]

I was pretty sure it was asked in a similar kind of post but couldn't find the thread, so here goes again, I want to add 4-6 Threadfin Cardinals in my new tank, but I like the orange lined cardinals a little more for the way they look, do they behave in the same way? or are they more of a pairing fish?

Latin names or pics of fish so we can be sure to be on the same page. What size environment will you be providing?

Zoramia Leptacanthus (threadfin cardinal) vs. Apogon Cyanosoma (orange lined cardinal) in my 57g

After doing some more research, it seems the orange lined aren't shoalers.

I would try 5 of the A. Leptacanthus. A dominant pair will push the subordinates to the corners. Keep your eye on them. Good luck.
