They would be in direct competition (conflict) with all of your shellies, who are going to need the floor space as is. I would pass on the Callochromis completely for your setup.
They'd be fine in your tank... if you didn't have shellies.[email protected] said:what about kilesa?
I think their requirements are slightly overrated. They did fine, and saw them breed a few times as well. Similarly, I've had Tiger Barbs breed under such conditions.[email protected] said:wow, how did you keep cardinals with them?
