wanted to know if this really is a M. lombardoi "Kenyi"? LFS called it kennyI. Also wanted to know are they good to mix with yellow labs? I have 2 yellow labs that were pretty calm before i put the "Kenyi" in there, and now it seems that the bigger Yellow lab is chasing the smaller one. I can see a little aggression now. I have a 30 gallon setup with one whisper 30-40 gallon filter.
