New to the forum, so thanks in advance for everyone's help.
I'm looking to fill out my 20 gallon tank. I currently have six whitecloud minnows (2 are fully grown, 4 fry are 4-5 months old). Since the whiteclouds usually stay in the top portion of the tank, I'm looking for something that will hang out more in the middle. Was thinking about 4-6 neon or cardinal tetras, but am open to suggestions. LFS
told me that cardinal tetras can be finicky - is this true?
