How Many Cardinal Tetras And Rummy Nose Tetra?

[J@son]

Hi all
 
I have a 270 liter community tank, recently my heater broke and most of my fish got white spot and unfortunately I spotted it to late and most fish died.
 
So at the moment i have: 2 kribs, 4 swordtails, 2 knight gobies.
 
I want to get two schooling fish the Cardinal and Rummy nose tetra. I want to know how many of each species in can keep in my tank?
 
thx

Answer: none
You cant. Kribs are a bit too aggresive for tetras

Assuming the kribs breed, at which point anything and everything in the tank is under threat. I don't feel that tetras are particularly under threat, since they are not primarily bottom dwellers. THe knight goby likes hanging around in caves and stuff, so would be a bit more vulnerable than a mid-water species.

I have had tetras with my breeding kribs before and it wasn't a problem.
