Wow, I forget there are people that have been in the hobby as long, or longer, than me on here sometimes.
I haven't seen one listed as a Pearl Scale in decades Mo ... brought a laugh seeing it again. Thanks! That's what we used to list them at when I worked in a LFS back in the early 90's.
Never seen them listed as a 'green texas' though ... blue texas sure, never as green. Of course, common names are different all over the place, hell sometimes even in the same city. I've seen a single tetra species listed under 3 different 'common names' all within the same town.
Not to mention a common name can be applied to an entire genus ... I've seen Media Luna labridens listed as 'yellow texas' and deppi as 'turquoise texas' ...
After screaming my voice hoarse at people calling Tapajos geo's 'redheads' instead of the common name of 'orangehead', I've given up trying to shout into the wind as it were.
The 90's? LOL Try the 70's. My point wasn't to dispute that they were called. I know people refer to them by the "flavored" Texas name. My point was that it would make much simpler to refer to the scientific name. When I see "ID Please" that's where my head goes. No offense intended to anyone. Common names and the new "pseudo" scientific names just make me crazy. You will never see me refer to a fish as a "manny" or a "jag", "red devil" etc. Maybe it's my age showing thorough. 40+ years of keeping cichlids and it pretty much sets you on your path.
Even in the same city, as I mentioned. It would be great if we were like you guys down there when it came to common names ... if there were a standardized list it would make life much easier since it's darn near impossible to learn to pronounce scientific latin (My college offered latin, but it was ecclesiastical latin which from what I understand is pronounced differently so I passed). But alas, we get all confused up by the twenty different common names plus the wacky names people make up (see redhead geo for tapajos above) to make it sell better.
I had not honestly seen 'green texas' as a common name for the fish before joining this site. So I wouldn't say that was the common name myself. With that name, I'd assume it was H. sp. pantepec or H. sp. poza rica.
If I ever owned a pet store, it would definitely be latin names for the cichlids!!!!
I will be the first to admit that even the latin names will bite you in the butt...with all the changes and reclassification's. But at least that happens less frequently. It's all good. Enjoy the hobby.
