ONLY way I'd ever believe anyone about Minis these days is IF I got one directly from the breeder that was able to SHOW me the lineage. EVERY SINGLE Marbled Motoro sold over the last what? 3 YEARS is supposedly a "mini". Comical to those that know the difference between a litter of Marbles and a litter of MINI Marbles.
Hybrids in general - same but worse.... ANY black ray blood at all constitutes "BD" these days. Do you really think someone out there is breeding BDs to mini Marbles? Would be a waste..... EITHER pure species is worth more. Most "Hybrids" being sold these days have a better chance at getting into VIP strip clubs in Vegas then for ANY of us to know the TRUE lineage.
The ray hobby has gone down hill is an understatement. Seems the almighty dollar has become more important then values.
IF the breeders were being properly supported in this hobby it wouldn't be what it is..... But everyone wants cheap - so you get what you get - a guess at best as to what species you'll be hanging on to till it outgrows its tank or owners interest.
