I forgot to add last night! That with that jaw shot, you changed my mind, technically malas jaw folds are suppose to come together at some point, this one doesn't. But it isn't that U shape either, it's like an australis, leading me to think it's a new species that belongs to the lacerdae group. I also feel like I can make out 5 pores, not sure though, 3 are definitely clear. Just my thoughts. Of course a number of things we've talked about with these guys are possible. And maybe it's cause the aimaras come from a bit of a harsher environment? And for the atf, do taft have longer dorsal fins generally? Or that's a hierarchy thing with them? And as for adding the big guy to the 750, well I don't have any personal experience with them but aren't atf a little more sensitive then say a dorado? Or this is when smaller only? Not many raise them like you to these larger sizes. Maybe he'll be more peaceful in there though? More fish to spread any aggression, and a bigger area to reduce it some as well? Just my thoughts, of course you know your fish better than anyone else, but it can be a guessing game. And that's interesting to hear about the intermedius behavior. Sorry for all the questions, I learn a lot from your input every time.
