Agassizii or Tefe'?

[Hellfishguy]

Picked up a pair of these at an LFS a few weeks back. They were very small when I first purchased them & I assumed that they were agassizii, but lately the male has started to look Tefe'-ish to me.

Not the best photos for ID, but I don't see anything that indicates that they are A. sp. Tefé. What make you think they could be Tefé?

Sorry I couldn't get a better photo; the male has been keeping a low profile since the female brought out her fry a few days ago. The male's dorsal & caudal resemble the ones I've seen in photos of Tefe' "Pearl Blue". They still have a lot of growing to do & I'm curious to find out which strain or species they turn out to be.

Caudal fin pattern on male Tefé isn't any different from that of many populations of A. agassizii. The main visible difference is that Tefé exhibits pronounce wavy lines on the flanks.

Got some better shots. Any idea which population of agassizii they are?

 

[Mike Wise]

Definitely not A. sp. Tefé. Looks like one of the Netz/Net forms of A. (cf.) agassizii to me.

Sweet! Thanks.
