Lemon Tetras keep fighting

[matt_wilby]

In my community tank I've noticed over the past couple of days that my Lemon Tetras keep displaying and charging at each other. I have 5 in total, the smallest is not a colourful as the rest so I'm assuming she is the female, this one does not get attacked (as much).

Capacity: 120 litres
Ph: 7.4/7.6
Ammonia: 0
Nitrite: 0
Temp: 26

Is there anyway I can stop this? Introduce another female?

TIA.

It certainly sounds like you've got too many males in there and that would be the reason for there inter fighting. Are there any other fish in the tank? Is the lemon tetra fighting strictly with there own species? Are any of the fish showing damaged fins or wounds?

I've got 9 Neons, 4 Bronze Corys, 3 Clown Loaches and 2 Gourami.

Sometimes the Lemons will attack the neons, but nothing else. Everyone else seems happy. Think I might try a couple more Lemons.

Thanks.
