Rainbows trying to mate ???

[cinciboy]

My rainbows are flashing color and dancing in between each other.. are they trying to mate ?

They could be going through a courting ritual. They could also be playing.

2 of mine are doing the same thing but one is slightly larger and it nips at the other sometimes. I'm not sure if it's aggression, wanting to mate, or what. :?

From yesterday onwards, one rainbow is hanging around plants always.. not much movement.. is something wrong ??
