Hi! I have 2 zebra danio females (I lost 3 of my original 5). I would like to get a few more schooling fish for them to hang out with. Is it best for me to just get a few more zebra danios, or would they still school with other fish (like other kinds of danios, or guppies, or platys)? If not danios, what other fish would you recommend combining them with? Or should I just keep with the danios (I have a 10 gal tank). I just wanted your thoughts on this.
