cardinal tetra school size

[Reddog80p]

Add a few more. However, don't necessarily expect a tight school. Aside from rummy nose tetras, my experience has been that tetras don't school very tightly unless they feel threatened, such as by the presence of a larger fish. Good luck!

What, no tight school? My tetras must really like meh then :headbang2:

For a 20g, I'd keep 12-15 of these fish.:hearts:

I agree. I have 26 in my 90G

I think 10-12 would be a good number.

Perhaps that's why my cardinals school so tightly... They're always in a neat little group, much tighter than when I had 20 maybe 6 months ago. (the tank was a community tank back then... cardinals, bosemani rainbows, clown loaches, gouramis)
