Help! Gachuas breeding or fighting?

[Timmy]

I bought three gachuas. Of which contained a breeding pair. Two of them hang togehter in a pot and ther third on the other side of the tank. At night i hear really, really loud splashing and one of the two that hang together has some tor fins. Is this natural? Help !

PS, this all happens when all the lights are off and it is dark.

How big are these gachuas? My gachuas did that from 3" to present in the 60. I think aggression is normal with these guys.
