Identification of A. Agassizii

[michaelrox]

Hello, first time poster. I bought 4 A. Agassizii (Red) at the LFS and have only had them in my tank for a little over a day. Comparing it to other pictures of Apistos posted on here I am unsure now whether it is an Agassizii that just needs to get adjusted to my aquarium or is a whole other species. Here are pictures of the presumed males and females, which I may be way off on.

I'm certainly no expert, and was just asking this question myself a month ago, but I'd bet money those are NOT Agassizii. They may be too young to ID, but the tail and dorsal fin markings are a dead giveaway of not Agassizii. Here is a website by Mike Wise and Tom C that is very interesting and a ton of help in learning and identifying:

Interested in what the experts say. My guess would be cruzi for the males.

Whoa....just a little ways from agassizii.

First two pics look to be fish from the regani lineage. A. paulmuelleri?

Last two pics I haven't the foggiest...

The caudal spot does look more like paulmuelleri.

Female is somewhere in the cf ortegai "Pebas" neighborhood?

Thanks for the help so far. I realize there are almost a hundred different Apisto species and finding out exact species will be pretty hard at this stage of their life, but from my understanding nobody thinks it is actually an agasizzii? Let me know if more pictures will help.

Thinking the same about the male, but the number of ventral stripes is a bit off... Maybe cruzi?

Pictures in good lighting and with erect fins (esp. the dorsal) would be helpful. Otherwise I'd say leave them some time to acclimate. Stress stripes and rests of juvenile coloration are distorting it for most of us.

The first two photos are male A. paulmuelleri. The third and fourth are atahualpa-complex species, probably A. atahualpa. Btw the substrate is not good for Apistos, fine sand is the way to go.

 

[Mike Wise]

I agree with Frank: A. paulmuelleri & A. atahualpa. Definitely not A. agassizii.

practically positive it is MacMasteri, if your store's supplier got it from an Asian tranship, they almost always call MacMasteri Agassizi
