LOL oh Tian-Tian was actually flaring
at his filter just now!!
I think the current scared him, though; he just went to hide and hasn't come back out since.
Well, it was worth the shot.
It's a really nice filter, though, and quite inexpensive, too. I kinda want to keep it just so when I do water changes and happen to kick up dust in the process, I can stick it in and run it until the water clears out.
Then again I can always return it and get my money back...
Edit: Okay, I just took the filter out. He was getting really aggressive towards it and I think it was just stressing him out more. It really is a nice filter, though. I might just keep it for future tanks/deep tank cleanings.
