So, I wasn't able to catch Hot Stuff in my 10 gallon, so I am breeding Bella with Lucky instead. They are in the breeding tank now. Mean while, my other neon tetras are stressed and paling because there are only 4 left. They look confused. Neon tetras are schooling fish, so you need atleast 5, although they do best with 7 or more. My neon tetras will be released into the tank tomorrow night. I set up the breeding tank to have specific qualities that will make my neon tetras breed.
