I bought a few tiger barbs yesterday and have introduced them to mym tank. this morning I have noticed that 2 of them appear to be kissing! I'm sure this isnt what they are doing but is this a known behavioural thing?
it is a sign of aggression, but more than that i cannot say, i'm sure someone with a little more knowledge of these fish will be able to tell you what it means, and how you can deal with it if it does develop into something more
i talked to a guy who used to breed kissing gouramis, and he said that the kiss signifies the border of the territories. Where they kiss is where the border is between two territories. As for tiger barbs I don't know. Maybe the same thing?
I do hope you are right! One keeps chasing another around so I'm thinking maybe I have 2 males & a female ... not that I know how to tell the difference!
the males should be smaller, and more brightly coloured than the females, apart from that I cant think of any other signs about their sex.
as jules says once they sort out who is the boss, they should calm down, how many are in your group a good number is around 6 I think. rather than just 3.
