Cryptoheros nanoluteus spawn

My C nanoluteus finally got serious and spawned. They've been acting like they're about to spawn for a while now....going in and out of a cave and putting on their spawning colors but I've never seen eggs. The male was still a bit small so I hoped they just needed to mature a little. Yesterday I saw them courting again but with a big difference....the female had her tube down. So I checked on them this morning and there are eggs in her favorite cave.

As an aside, nanoluteus, sajica, septemfasciata, myrnae, nigrofasciata, "Honduran Red Points" and the other "convicts" (siquia, kanna, etc.) are all Amatitlania...while only the "spilrum / cutteri"-types remain in Cryptoheros.

They're hands-down some of my favorite fish (both Amatitlania and Cryptoheros)...which is why my fishroom is full of them!

Thanks, I recall that there were some name changes but wasn't sure where things officially stood.

The big changes came with the publication (a few months ago) of Říčan, Oldřich & L. Piálek, K. Dragová & J. Novák. 2016. "Diversity and evolution of the Middle American cichlid fishes (Teleostei: Cichlidae) with revised classification". Vertebrate Zoology. v. 66(n. 1), pp. 1 – 102

http://www.senckenberg.de/files/con...-1/01_vertebrate_zoology_66-1_rican_1-102.pdf

The Cichlid Room Companion (among others) have begun using it, so I'm (still) trying to learn the new names :)

It's a bit of an intimidating paper because of its length but the bottom line is that this is the most comprehensive and complete molecular analysis of Central American cichlids ever done.

What's also impressive is that, in creating phylogeny (the tables that describe the origins of present-day species and their ancestors) the authors used multiple methods - the latest genomic analysis methods, older ones, morphology, geography, etc, identified where different methods resulted in different results and worked to reconcile them. The "new" genera (and moving of species from one genus to another) are based on all of this work.

So long story short, Amatitlania now has a bunch of species ("convicts and friends"), Cryptoheros now houses the spilurums and cutteri-types (only) and Panamius is the genus for the fish formerly known as Cryptoheros panamense.

This would be a great Wayne Leibel presentation!

Eggs looked great, I saw 2 or 3 that had fungused but it didn't look like it had spread. All seemed normal. I'm pretty sure I even saw wigglers. Then they were gone. I was hoping the parents had tucked them in a corner of the tank under a leaf or some wood to protect them until they were free-swimming, but I never saw any. I'll let them try again before I intervene. Maybe I need some dithers.

They're super secretive fish. If they've turned back to normal coloration, chances are the eggs are gone (watch out that the male doesn't kill the female!). Otherwise (if they're still colored up), they're tucked somewhere and you just have to wait.

Another way to trigger the parental instinct is to add a 3rd wheel Nano (or other cichlid) in a net breeder (or behind a divider).

Would be great to have some of these guys for my new fishroom :)

They dimmed down for a day or so but are colored up again. I'll kee watching the tank.

I actually have a third nano....a female. I had removed her because she was seriously messing with the main pair's mojo when they'd go to spawn. I'll add her back in and see what happens.
