Clown won't share anymore?

[bassman]

I purchased a pair of clowns about a month ago. I also bought a BTA at the same time.

Until yesterday the clowns seemed to like eachother, always hanging out together and sharing the BTA.

Now the regular perc is biting at the true perc every time he comes near the BTA. Any ideas why this would happen after a month?

Nothing has changed in the tank, aside from the addition of a 6 line wrasse a couple of days ago. However due to my lack of intelligence he perished yesterday while I was cleaning my over flow box. I forgot to put a cover on my power head while I had the over flow box apart and he got sucked in :-(
Ever feel like throwing up? I hate when my stupidity costs a little critter his life.




Thanks
