Tetra grouping

Is it normal for 2 lemon tetras to group together all the time and leave the other one out of the group or is the pair a mating pair and trying to do a breeding ritual? What is the way to tell the difference between male and female lemon tetras?

I guess it depends. Sometimes they may exclude one another from the group. It happens with my fish sometimes and then other days they are all in a group. They may be breeding, though, in which case when they get done, they will probably all school up again. do they normally school together?

g'morning Tom~
I was wondering the same thing. I have three tetras newly introduced. They usually hang out together but at times, I see two together and one seems to be left out, by him/herself. Cant tell at this point if its the same two either. Wish I could tell the sex of the tetras as well, and hopefully someone out there can give us a clue! I think with introducing three more, will solve the ' One is a lonely number'.. issue! That's what I'm going to do.

 

Shortly after writing this post, I got three more and they all school together and look happy since they swim along side with my big angel fish.

that's great news Tom! ;D I wil also be adding angels, but not til I get the water situation under control.
I bet your schooling tetras are very happy!

 

They are very happy, and will be even happier when the new tank is set up.

Well... My neon tetras do the same thing. Being a newbie and all all I can say is that if no aggression is being shown and the fish is eating they're really is nothing wrong.

Our diamond males chase the female all over the place when they want to breed.
