I'm thinking about adding a school of 12 or so Blue Tetras to my 125g tank, but I don't like it when fish are just all over the place by themselves - I like at least a semi-cohesive group. How do Blue tetras behave? The tank already has Buenos Aires and Columbian tetras.
Well I couldn't wait - I have the shopping bug today. I ordered 12 at $1.49 each, they will be in Monday, so I have to get a QT tank up & running fast! I'm using the one I have now to grow out the Columbian Tetra fry. I'd still love to hear what people think of them, so if you have some or have seen them, please chime in - thanks!
I had some of the Cochu Blue tetras if thats what you're talking about. They schooled together nicely, with a stragler off on his own every now and then. I had 5 in a 20G so I think they will be just fine in a tank like yours.
