We recently set up a new 29 gallon tank and got 5 of these guys and wow! what a difference they made in our tank! They are so active and outgoing as quite a few of the fish we had chosen tended to hide. They have livened up our tank, and actually made our other fish more outgoing. The blue stripe along the back is stunning, and it is awesome to see them school. They are active and eat well and are my favorites in our tank!
Beautiful, Fantastic Tetras

I got 5 of these little guys (well, they were little then) along with 5 Buenos Aires tetras a little more than a year ago and they are all going strong. Once they got settled with their new tank they became really stunning little fish. Their silver bodies reflect light almost like a new coin, the blue down their backs is very vibrant and their fins are a deep, nearly opaque, red.
They school beautifully with the Buenos Aires tetras and are generally very calm, mellow fish. The only time they get wound up is just before dinner time. Then suddenly my docile, slow little beauties turn in to athletes and race around the tank at top speed until dinner is served. It's quite fun to watch.
They seem to be a very hardy fish and not too picky about pH levels.
If you want to research them just to be sure they're right for you, they can often be found under the name 'Columbian Tetra' as well as Red-Blue.
They do get to be on the large side for tetras so be aware of that when considering the size school you get and they will eat smooth leaved plants like swords. Other than that I'd recommend these guys to almost anyone with a tropical community tank, even a beginner.

These fish make a nice addition to a community tank. I have never found them to be aggressive. They add a different size and shape to your tank. Mine is 75 gallons so space has never been an issue. Having said that I think any size tank would be okay for them as o
long as you follow the "1 inch of fish per gallon of water" rule.
Typical large tetra.

These guys need a big aquarium because while they might not get super big, they are powerful swimmers. My skirt tetras were terrified now that I think back on it. I've never seen my fish school so beautifully (fear?), but then I took the 3 Red-blues out because my 30 gallon felt too small for them seeing aggression. I would get these fish again if I ever set up a big semi aggressive tank and could get a proper school of them.
