I have a bd that will head bob evey now and then a few times a day. this is the first time that i noticed her doing it. i do have a second baby bd that i have had for about 2 weeks now but the bd doing the head bobbing cannot see her bc of where her cage is located and that i have 3 sides of the babys tank enclosed around it.
does anyone have any suggestions why the older bd is doing this?
