A. elizabethae?

[Eddiekay1010]

Hi, another group I believe has been mislabeled, they were supposed to be A. elizabethae but they have a lyrate tail, which I think elizabethae lack. I have Romer's books, but there are a number that look similar and I'm not confident in my ID skills. Could not get a picture of any females, but they're in the tank, it's just densely planted, heres some pictures of the males.
Thanks

Hi, doing more research, I am seeing some with lyrate tails, most of the photos in my books, they looked more spade shaped, similar to agassizi, I'm more confused now, thinking they could be elizabethae

They are

Thanks so much, do all elizabethae males have that lyre tail and its just that in some photos the caudal isn't fully open or do some localities have the agassizi like spade tail?

The shape of the caudal is variable. The spade like shape can develop from the two tipped one as the specimen grows older or it just stays two tipped.

The brook A.Elizabethae comes from has two collection points, one upstream where they have a blue-grey belly and tend to have a spade tail more often. At the mouth of the stream is where the red belly ones are and tend to have the lyrate tail. Note people selling them as "super red" are not breeding a line they simply have the naturally red belly ones.
