5 tetras

[BAT]

I bought 6 tetras and 1 died.  Can i keep the 5 as a school or do i have to buy 1 more?  Background - they are in a tank with 7 black tetras and 6 neon tetras.

They will probably be fine as 5. All your groups would probably exhibit different behavior with more of the same type though.

5 is ok. But the bigger the school the safer and less stressed they are. If you have enough room room you might want to add 6 or 7 more. Depending on the toe of tetras they are

I agree with everyone else. The bigger the group, the happier

Do different tetras school with each other?

[anitstuk]

I don't think that they intertwine but they can school in the same tank

I would watch them personally and if I felt their behavior wasn't quite what I wanted I'd get a few more. Their bioload isn't big and if your tank is stable it shouldn't effect it adding a few more (whatever your LFS sells them in small groups for I'd do- like when they say 4 for X amount of $). My Harlequins (10) and Black Neons (also 10) hang together and school when I approach the tank.

What kind of tetra?

I'd probably stick with the 5 and only buy more if I decided I wanted a lot more. But 5 is generally a reasonable group
