you mean you don't trust random Vieja purchases not to be pure-strains? C'mon now, people don't just LIE and say it's not a hybrid so they can make a sale PSSSSSHHHHH, nobody does thatIt has none of the spangles to the head associated with hartwegi. It also displays the block/window type pattern of fenastratus. it has also reached 14 inches. Hartwegi are seldom recorded over 12.
I also think fenastratus is the closest natural match to this fish but there are no guarantees it not a hybrid.
As per other thread,I think your wrong.
