I bought some neons yesterday. they have been fine so far but now they have started chasing each other around and it looks as if they are nipping at each other (however i am not sure if they are actually nipping). Is this normal?
Thanks, John

They are more than likely just establishing an heirarchy within the group. Who is the leader, etc. Or it could even be harmless chasing. Nothing to worry about IMO. How many do you have?

What size tank are they in? Do u ahev any plants in there with them?

There are 6 in a 25ltr tank and i have 2 large plants.
thnx for your help.

I do not have any other fish in there.

It sounds like you are perfectly stocked in my opinion so congrats on that. You could maybe go a few more depending on your filtration. Personally I think they are doing each other no harm and you should not worry about them. Also why don't you go ahead and register?

Thanks for your help. But i cant register because im only 12 and my dad wont let me. Thanks again, bye.

Tetras are best kept in odd numbers of schools of 5 or more.

Why odd numbers?

Mazza hit it on the mark. All normal stuff for the Danios.
