The longer I collect, and more and more cichlids I witness in nature, it seems I tend to have to constantly revise my expectations of what a cichlid tank should look like.
In the past, and as a general rule I have considered tetras to be little more dither fish, (because the bulk of my interest and obsession) is in cichlids).

My intention for tetras in the past, has simply been to have as dither fish to keep my prize cichlids tranquil, and as a result they get relegated to that mere secondary role. Although the realities, and the revision of my perception, get atwist when visiting nature, because I see how they play a most integral role and are almost always, the largest piscine component of the natural habitat, and ecosystem, at least here in rivers of the new world.


Being cichlidophiles “I/we(?)” often want to cram our tanks chock full of many species of cichlids (sometimes to our dismay, ending up with less than stellar or edenic results).
But the reality is (at least in nature, in Panama where I live) that muti-species approach, is quite far from the reality.
In the rivers I frequent here in Panama, I often find only 1 species of cichlid (maybe 2, if I’m lucky) in a couple acre stretch of river, and those two species may spend the majority of their time in vastly different habitats within that same body of water.

An example could be Andinoacara coeurleopunctatus (Knee. 1863), and Darienheros calobrensis (Meek and Hildebrand 1913), although both are found in the same stretch of the Mamoni river. Yet I almost always find the Andinoacara in slower moving water, in deep pools, and in sheltered, root crammed banks along the rivers edge. Whereas the Darienheros are most often netted in faster flowing areas, in mid stream (especially the mature adults).

But beside that cichlid species population and habitat disparity, for each individual cichlid I do catch, there are usually more often hauls of 50 or more tetras.
To me this is telling, and might be a more proper concept to consider in the way we cichlidophiles tend to approach our concept of proper tank stocking.

African Rift Lake cichlids, of course, are a totally different matter altogether, living together in diverse communities in the rift lakes.

How many cichlids in the video above.
 
I've come to normally prefer a limited number of species in my tanks vs. an a la carte approach of one of these, one of those, one or two of something else, adding up to a bunch of different species (the exception to this being whatever plecos I have in a tank). If not a species tank, I typically prefer the look of a plausible community (again, limited number of species) though for me it doesn't have to be a location-accurate biotope of species. But what drives me nuts is the compulsion of some to shoehorn certain fish into every conceivable mix, like putting clown loaches together with everything from soup to nuts. Admittedly, though, there have been times I was breeding several species, raising many beyond the juvenile stage, and with only so many tanks some would temporarily overflow to wherever I had space and create a geographically anomalous mix.

That said, I watch a ton of wild video, mostly SA habitat (occasionally CA cenotes, because they can be beautiful). I find this educational regarding our fish in the wild and one thing I see is how many (and which) cichlid species are found together varies with location and habitat (or season) and that they vary in proximity and interaction. This agrees, for example, with Heiko Bleher's articles on discus habitat, where he lists the other cichlids he sees with them.

I count 5 cichlid species, here-- Cichlids in a tributary of Kourou river, French Guiana - YouTube

Starting about 7:30: "under this fallen tree there is a really nice mixed community with many of the cichlids we saw earlier... likely you also notice that this whole community actually functions kind of well."

What is interesting to me, is to see the different contrast between (not only African cichlid biotopes) but South and Central American cichlid biotopes.
I agree, when I was in Colombia the difference between varieties of species combinations there, compared to the much fewer combinations that I see in Central America. was quite eye opening
In Amazonia, maybe it's because of the vastness of the aquatic habitat, or differing water parameters compared to the more compact harder water habitat in Central America.
But it is also similar in S America west of the Andes.
Where in Peru, and Ecuador west of the Andes, its difficult to find more than 2 or 3 species of cichlids, yet east of the Andes hundreds may be found.
And your analogy of discus habitat with 5 species just goes to show that.
Yet west of the Andes, only Andinoacara, and Mesoheros cichlids may cross pathways in the same river.

I use Rainbow Danios for my dithers; tetras always seemed like to easy of a target for my other fish
Interesting, I may now consider adding tetras, instead....
Rainbow Danios??
 
  • Haha
Reactions: jjohnwm
yes, Rainbow Danios. I'm so old, they're probably called something different, now.

Yeah, I think they're called Zebra Tetras or Paradise Barbs nowadays...

Never heard of a rainbow danio, I may be a young fella but i've read a lot of aquarium history and a fair amount of Dr D**khead's atlas of aquarium fishes, and not once have i seen a rainbow danio. Right now I can only think that you've got rainbowfish or giant danios.

You got yourself some hybrid rainbowfish right there. Melanotaenia sp.
AHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHH!!!!!!!!!!!!!! I hate hybrids. That mother plucker sold me a fake fish with turned out to be a hybrid. Thank God, they're essentially fish food.
