Nothing big, just want to say that I have almost fallen in love with cory's. A few days ago a tiger barb was added to the community tank, that tiger ended up eating the long part of my swordtails tail.
Since this happened I've noticed that the tank has split into 3 group type things, The sword tail/cherry something go and hide with the Cory if the tiger barb gets aggressive, the and the neon tetra's. Since the tiger barb tends to get aggressive from time to time he will chase the cherry and swordtail. They go and hide in a skull decor, that my cory lives in. The second my cory see's the Tiger any where close to his skull he will come out and chase the tiger barb away head butt him a few times them go back to the skull. The tiger barb doesn't do it again.
I also noticed that my Cory hates the tetra's I think he feels they will ruin his skull, because when they come into the skull and he notices he will head butt at them to get rid of them.
