Guys, I'm beginning to think that my original assessment of this species from way back when may have actually been correct: this might be rutilus.
As my girl Dottie grows and grows, she keeps growing. For a supposed dwarf goonch, that's an issue lol. The literature states that the dwarves are not supposed to exceed 8", but as I was doing my most recent water change, I was able to measure her. She was just a hair under 10" long and a bit longer even, if you count her streamer.
Plus, her fins are getting to be a very bright yellowish orange.
