Fish Fight

[checkvalve]

My Lemon tetras have recently started to get really aggressive towards each other. Is this common?

 

[Puriti]

Most tetras just like to pick on each other. Are they charging and nipping?

 

[Primetime]

Depends.. Are they in a school of atleast 6? If you're keeping a low number, like 3, the dominant one will bully the others.

I have 7 and they were all introduced at the same time about a year ago.
