This posting is as "deep" as the Discus thread.
I'm not keeping these guys because I believed, as I was told and had read, that they are extremely docile and laid back....good for a community tank. They ate two of my rummynose tetra (my fault...they were too small) and then beat up a few of my Roberti tetras killing one. A cichlid is a cichlid is a cichlid.
This might be a good time to put them for free in the "For Sale" area of the forum.
