I have 9 cardinal tetras that I've decided to try and breed. I did a little reading and it sounds like I need: RO water or rain water A small tank with about 6" of water A mop I read I should condition the fish in one tank and then pull them and put them in the small breeding tank when I have gravid females. Daily water changes and no feeding the adults while they are in the breeding tank. One source said they should spawn in 2-3 days. They also suggested an anti-fungal. Would Methylene blue be okay? Now I'm blanking on what they said about temp. Does 82 seem right? Does this sound right?
