So I've had my black ear pangasius for a little while now, and he is starting to gain confidence as a member of my tank. However, at random times, he'll go absolutely nuts for no reason. He will swim from one side of my tank to the other at lightning speed. He'll hit the glass so hard I can hear it. I've heard they're very skittish, even more so than the iridescent shark. I don't have a top on my tank currently, and some of his movements could easily thrust him out of my tank. I'm not scaring him- I approach my tank slowly each time I look in, and I keep my distance when I'm not-and I'm avoiding any circumstances in which he could get scared. His nose now has some red on it from hitting the glass, and I don't want his nose to be ruined. Any idea of what's spooking him? Any advice would be appreciated.
