Just got thinking about "red dwarf" frontosa, whatever that's supposed to be.
There is a legitimate fish from the lake that's considered a sort of dwarf Cyphotilapia, "mbete blue" from Zambia. (Technically, it's not a C. frontosa but a C. gibberosa-- just like the Zaire blue types, mpimbwe, etc. (Cyphotilapia in the roughly southern half of the lake are gibberosa, distinguished by different facial markings, scale counts, etc. C. frontosa include both 6 and 7 stripe types in the roughly northern half of the lake.) In any case, mbete blue are rare in the hobby (and not popular or well known). Doubtful anyone who's taken the trouble to acquire them is the type who would somehow try to turn them into 'red dwarf'.
If Anthony mentioned above is PCCA Anthony, then he has had mbete blue (and he
called them "mbete blue") and he knows as well as anyone some of the legitimate wild Cyphotilapia types with color adjectives sometimes attached to their names. If this is the same Anthony I'd have to think the above comment was sort of off the cuff with unintended consequences or else possibly misunderstood.
...In fact, if it's the same Anthony, his name on a well known Cyphotilapia forum is "Zaire Blue".
Mbete blue males reportedly top out between 8-10 inches last I heard; large males of most other Cyphotilapia types can be 12 inches plus.
