Recently I've added some floating plants to the corner of one of my tanks to give the gouramis some shade. Initially it was fine for the first few days, but today I noticed that the male would like touch mouths with the females and then chase them across the tank. I'm not sure if he is being territorial because the guppies kinda just do their own thing near the plants and he doesn't seem to care. Would it be that he is preparing to mate? His belly also became really red recently.
