New clownfish, swimming funny?

Well, I can't watch because youtube is unavailable at work, but bobbing is fairly normal for clownfish. They're all kind of goofy swimmers.

 

It's normal.
That's what they do when they live in a host. They kind of bob up and down into and out of an anemone...

 

I noticed that same thing that you did. Whenever she isn't intentionally swimming down, then she starts to float up front first. I hope i'm wrong but she may have a problem with her swim blatter, or air blatter, i don't remember which it's called, but they use it to control their buoyancy. If that happens, it's usually then end of the fish, that's why i hope i'm wrong.
good luck,

i'm glad she's doing better

 

Ya they love brine, but make sure you mix in some other food (mysis flake) over time. I was told brine shimp are very low in nuitrients. Like candy to us...

 

How big are your clowns? Did you just get them? The first video reminds me of when mine where new and the female was expressing its dominance over the male. During this time the smaller male ate very little this lasted about a week.

 

Actually, like all fish, it is best to feed them a wide variety of stuff. Clowns are omnivores so they will eat meat and veggie material.

I feed mine generic flake food, formula 1 and 2 flakes, formula 2 pellets, prime reef flakes, mysis, brine, tubifex worms, a krill now and then and seaweed salad now and then. All of the tank enhabitants will munch on just about everything I put in there.

The urchin usually takes care of the left over plant material while the spaghetti worms and crabs take care of the rest.
