Thank you. The way the filters are in my tank, one side has faster water flow. It is interesting to see some of the fish I had even of the same type that chose which water flow area they liked best. Do severum stay more mid level? The tank flow is also lower mid and upper level than low level. I have a large HOB filter on the end of the tank and it sweeps water to the bottom of the tank.View attachment 1550559
Here is an exampe of what mean.
Above is a habitat in Colombia where you might find slack water cichlids like severue.
Below is a rheophillic habitat where you would find Geophagines.

Would the Congo tetras be a better choice?One other thought, Denison barbs come from cool mountain streams in India and do best at temps in the low 70sF,
whereas the cichlid species you mention from Amazonia would do best in temps of the low 80s
Interesting things to look into. Thank you!Yes
I would consider Congos are a better choice, because they come from similar tropical temps, and from soft, low pH water conditions and parameters
But ..... just my particular bent.....
I try to keep keep fish together that belong together in nature (geographicaly),
as an example....I would only keep South American species with South American species from the same areas.
or
African species from the same lakes or rivers with those Africans etc, etc
An example of I would "not do", is keep cichlids from the temperate conditins in Uruguay or Argentina, with tropical species from Colombia or Venezuela.
In my own fish keeping, I'm even more biased and anal
I keep species from only the same river systems in Panama together,
If I collect species that "don't live together in nature", I feel like I would need to start a separate tank.

The 2 riverine cichlid species above, come from the Rio Pacora and its tributatires in east centra Panama, near the Darien, water temp 82"F(average,) pH 8.2, and undetectabnle nitrate. They share habitat with Astyanax and Roeboides tetras, Awaous gobies, and Chaetostoma Plecos, among others

I realize this is not the normal focus for most aquarists, but that's how I roll.
Cichlid (Chogorro), in the Rio Utive, Panama
Very nice looking fish!Here are a couple other examples of geographical biotope tanks.

The cichlids above are only found in Lake Barumbi mbo, in Cameroon.
The tank below, contained only cichlids fro Uruguay, situated on a north wall, to take advantage of cool temps, in winter.

That would look nice! I loved the Congo tetras I had before. Thankfully, they are easy to get here in the US.If I didn't live here in Panama (where there is a lack of access to more exotic species), I would love to do a large Congo river biotope tank with Congo tetras, Heterochromis multidens, Teleogramma depressa, and one of the Steatocranus species, such as casuarius.
