Hey All. Is it normal behavior for a Yellow Coris Wrasse to hang out at the surface of the tank and splash like crazy? I've had this fish for about 6 weeks. Haven't added anything new. Fish looks great and is eating great. I have an open tank. About a week ago, I noticed all kinds of salt dried on the top 1.5" of the tank above the surface of the water. Finally realized, it was one of the fish splashing. I thought it was my Longnose Hawkfish at first, but then all of a sudden noticed it was the Coris Wrasse. No one is harrassing him at all. Parameters in the tank are fine. I didn't notice him doing this until the past week. He's mainly staying at the top of the tank which he never did before, and swimming in place, but back and forth, really fast, and every couple of minutes, creates a big splash. I'm sitting about 5 feet away on the couch, and he just splashed me all the way over here. I can't have dried salt all over my couch and carpet if he's going to splash constantly, so I guess I'll need to bring him back to the
LFS if he continues this. Wouldn't be an issue if it was a covered tank, but it's an open Elos tank. I also can't keep the tank clean with him splashing like this either. I clean off the dried salt and then an hour later, the top of the tank is covered again as well as the glass on the light fixture. All fish and coral look great. I can't really think of anything that has changed that would be causing this kind of behavior. I did swap out my
T5's a few days ago with new bulbs (and lowered the
photo period), but I think this behavior started a few days before that.
Hmmmm... he hasn't moved from the surface of the water for hours, except when I fed the tank and he ate well, and the
MH light just shut off for the night. The
T5's only are lit right now, and he immediately came down from the surface, and is swimming around like normal now poking around on the rock.
Strange! If it was too bright for him with the new
T5's and the
MH lit, wouldn't he go to the bottom of the tank, not the top? I never really saw him behaving like this until the past week.
MH bulb is about 6 months old. Should I try raising my light fixture? It's currently about 9" above the surface of the water.
