I have 2 bumble bee amongst other different cichlids. 1 of the bumble
bees recently has become very dark in color, more black than yellow. And
it has been in an unusual mood. He keeps chasing the other bumble bee
around, zipping around back & forth across the tank. And than bullying
the others in the tank if they get in his/her way. I don't know if he is
simply picking on the other bumble bee or if the are mating. What do you
all think? Thanks for any tips..
