I got these fishes from Brian few weeks ago and they are starting to show nice color recently. They look a bit different as the photos on TomC's website.

Maybe they are still too young to identify?

Ignore color. Other characteristics seem to be the same as those seen on the holotype (Río Mazán) form of A. cruzi. The body seems a bit deeper/more high-backed, but this is probably due to being in a domestic environment.

I took some photo while doing water change last night. I was aware that one of the male curzi showing red color on his belly and looks nice.

By the way, what's holotype mean exactly for apisto?

Thanks,

Yu-Cheng

Hi all,
By the way, what's holotype mean exactly for apisto?
It just means that it is a similar fish to the original scientifically described "type" A. cruzi specimen collected by Sven Kullander from the Río Mazán.

The holotype will be preserved in the Swedish Museum of Natural History, and researchers would be able to compare fish that they have collected with the holotype.

There is only one holotype specimen, although a series of similar fish may have been collected, these are "paratype" specimens.

The reference for "A. cruzi Kullander, 1986" is:
Kullander, S.O., 1986. "Cichlid fishes of the Amazon River drainage of Peru". Department of Vertebrate Zoology, Research Division, Swedish Museum of Natural History, Stockholm, Sweden, 394 p.

There is a more complete discussion of holotype, paratype and lectotype in this thread <"Apistogramma agassizii....">.

cheers Darrel
