Calming Community?

[bucsfan914]

personally i like watching my school of a dozen cory catfish swimming around...they are calming and they are very active

 

[Ethos]

I also like cories, and I think I'm going to get some more of them too.

But for tetras.. There has to be like 600+ species.. and only 5 have been mentioned? Is there one that maybe isn't so commenly know and owned?
