How many of you keep this fish?

I know we have disscussed it before but I never got who actually keeps them.

The reason I ask is because I'm thinking of getting some when I place my next order of fish.

The last time I kept them was 25 yrs ago and never saw them for sale again.

A couple of questions; I kept them in a community Tetra aquariam at 80 F and thats what I have now. Most articles say they like cooler water around 76 F so will they be comfortable in my Tank? Also supposed to be more sensative than the Black Phantom but I did not find them to be. If you do find them sensative, in what way? Cardinal Tetra sensative or better or worse?

Thanks in advance for any advice.
