I’m leaning more towards Amphilophus hogaboomorum he is showing more color now, bit of red under the chin and gills as well as the orange pectoral fins.
Well with the barring it's not chancho/zaliosus at least, viridis/astorquii/globosus/supercilius/tolteca/the other 10+ undescribed proposed species aren't in the hobby to my knowledge, obviously not pure labiatus, and it's not yellow/snout too long so it's not amarillo, so that leaves us with (in regards to pure species), citrinellum, xiloaensis, flaveolus, and hoga. All of these have orange chins, yellow/orange pectoral fins, and 7 bars + a dot on the peduncle.
Hoga, xiloa and citrinellum are basically identical/only really distinguished from eachother by location, as hoga is endemic to one river in Honduras, whereas (what is currently described as) citrinellum is native throughout the main great lakes in Nicaragua and through most of northern Costa Rica. And then of course xiloaensis is only native to lake xiloa. Flaveolus is a weird one because its diagnosis compares it against chancho and astorquii... which is a pretty clear process of elimination in the hobby if you only had chancho and flaveolus. So again that becomes a matter of locality. Dan at COTA and sometimes wetspot are the only ones I know of selling/sourcing pure Amphilophus. As you may know Dan is no longer in operation but may still wholesale to some stores. He sends mixed boxes to stores, usually only a few of each species and probably not enough for another retailer to use as broodstock, and for what they're worth I don't think they'd leave the labels off.
Essentially, again, without locality info or a species label you can't 100% tell what this particular fish is. More than likely if you got 12 of them at roughly that size as "bycatch" in a shipment of mixed african cichlids they are not something with a known pedigree, and are again, likely just what we in the hobby call "midevils"-- mixed Amphilophus from back before a lot of the Amph. sp. were described, and everything was either a red devil or sometimes a midas. Purity wasn't of as much value back then, so people bred them all together.
That aside this thread has me craving chancho again...
