Hi, I have a newly set up tank (1 week ago). The tank is a large 330ltr corner tank.
On setting up my tank I added some mature media to the filter and 4 rainbow cichlids.
I have been testing the water daily, no traces of ammonia or nitrite so today I have added a britlenose plec.
The Rainbows have been swimming about and feeding together in harmony all week. Today though I'm surprised to see that one of the rainbows which is slightly larger than the other 3 is constantly chasing the others around the tank appearing to be aggresive. I wasn't expecting this and wondered if I could just have a bad tempered one or there could be another reason for this, Mark.
