Cardinal tetras

[Anna94]

I bought 5 cardinal tetras cuz the lfs had a deal for 5. I wanted to buy one more, but I only had so much money. Will they be ok cuz I know they're supposed to be in schools of 6 or more. The other fish that are in the tank are 2 platys.

They'll be fine. Like most tetras, they're happier in larger groups and you'll see more interesting behavior, but they should do well.
