matubula;3564911; said:LDA63 are juveniles of L27. Im fairly certain that a very experienced Singapore fella proved it by buying LDA63 and growing them up, and then they were then considered L27 Xingu.
Just a side note, L27c is quite a vague term now for L27 because ones from the Xingu, Tocantins, Maranhao, Aruguaia, Tapajos have all been erroneously given L27c.
Are you trying to find these fish?
matubula;3564975; said:LDA63 have the rusty/red colour to their dorsal, pectoral and pelvic fins, they also usually have a very large window bar if not completely clear on the caudal fin. They mature in to the L27 Xingu also know Platinum Xingus.

They lose the rusty/red colour and their caudal fin 'colours up' as they mature. Goldlines are also called L27c and they come from the Araguaia, Tapajos and Maranhao.
