First: love your user name - we are cat people too
They are commonly known as "frontosa" which is not totally accurate as their species name is "gibberosa." Full name is: Cyphotilapia gibberosa (Zaire Blue Mikula). Mikula being the collection place where they were rounded up in Lake Tanganyika, Congo, Africa.
"Nyatzi" is Setswana and it is translated "the lover." I don't know how to write in phonetic characters.... the N is long and the rest is pronounced like the game Yahtzee. Emphasis is on the N.
You have to be careful what African name you give your frontosa because they will live up to their name. I once named an Alpha male, Ntchwaidumela "He who greets with fire." He proceeded to kill six of his siblings. From now on, they get more peaceful names
The alpha male in my 240-gallon tank is named "Tau" translated "lion" and the subdominant male earned his African name when he snuck in a spawn with one of Tau's females. His name, "Ntate" which is translated, "Father." I have fun with it.
