I hear you on lemons being less nippy than some tetras. We kept serpae early on & they were pretty bad fin nippers. I always worry about "high bodied" tetras especially...but really almost any tetra can become that way in the "wrong tank" or with the "wrong tankmates". We had neons nip bettas; those long flowing fins are hard to resist. We used to buy a dozen tiny juvenile neons
You know, I've never kept embers partly because they look like tiny serpae
& the betta might eat a few. I truly do understand they aren't similar in behavior because they're similar in color & shape. Maybe someday...
