I have 9 (started with 12) buenos Aires in with a ebjd Male and green terror female and they do great, even bred. I had columbian tetras in there to and they did okay but I moved them out as it seemed they were struggling more
Largest tetra for dither
- Thread starter Thalassa
- Start date
Another large "tetra" that can be considered are Triportheus spp., including one that I have kept before, T. angulatus. Triportheus spp. ('hatchet tetras') get large (4-6" depending on species), are mostly surface to midwater dwellers where they eat primarily small insects in the wild (but they will eat everything). They are so fast and self-assured that are likely to succeed at avoiding even major aggression attempts by cichlids, which would be more towards the bottom anyway.
The most common Triportheus in the hobby is T. angulatus (not than common but frequently available online) stay at the 4-5" range, as it is also one that can can take slightly higher pH and hardness (the others are thought to be restricted to soft waters). I kept T. angulatus at my home conditions (7.5 pH and slightly higher) for years, and enjoyed the heck out of them. They did very well on those conditions. Whether they can take the water conditions that are best for green terrors and Jack Dempsey is an important consideration, but I suspect they may do Ok, at least at a compromise range of values.

All would work out well. I’m partial to the BA though.
I had looked into all three when deciding on dithers for my cichlids, but I went with BA because I already had some in a different tank that I could combine.
If you want something more colorful, go with the Colombians.
BA get really stocky and hold up to my jd, con, bp, and Leporinus very well, as well as aggression from the Aussie rainbows they are with.
I’d expect a similar story with redeye.

Tetragonopterus argenteus aka redfin argenteus tetras are what you want. Smaller than SD but larger and more robust than the other tetras mentioned here. They're normally pretty hard to find but several online vendors appear to have them in stock right now.
Here is a group of nine I kept dithering the hell out of a 150 mixed community tank:

They likely would all work together. Most tetras of similar size and aggression seem to play nice.
Beautiful - they look like wimple piranhas!
Are these the guys sometimes called “silver dollar tetras?”
