I bought these guys about 2 months ago at 1" from a local shop as f1 bahia kelberi they are about 5-6 " now how long does it take for their fin spangling to come in are they even kelberi?
You might start seeing spangling at around eight inches and I'd go with them being bahia as just about any shop should be able to get them.
The top left fish in the bottom photo looks like an orino.
