Colombian Tetra Breeding Habits

[Tonyb111111]

Does anyone have experience of breeding Colombiam tetras, as mine are behaving a bit strange lately, in a good way. They appear to be shoaling much more than usual and there is a lot of tear arsing around. Can anyone advise?

Has anyone out there got any ideas. As a point of interest, a got a shoal of diamond head tetras yesterday and the Colombians appear to enjoy his new edition tremendously

Does anyone have Colombians that can help explain the behaviour that I'm seeing. I am not worried about it as they seem to be positively glowing, just curious bout the behaviour
