Hiya, I just have a quick question about my zebra danios. When I look closely at two of them, they seem to have little barbels ... but any of the pictures in my books don't seem to have any?!? Also, these ones seem to be a little bit territorial! Nothing too agressive but they've kinda made areas of the tank where they like to hang around and they chase after any of the others that come near them! But only their own kind ... I have platys and guppies in with them and they don't seem to mind if they come close to them! Maybe this stuff is normal, I was just wondering!!!
