Clownfish Behaviour

[Gujustud]

Well after almost 3 months of waiting (since I started my tank), I finally got my first 2 clownfish (percula). I picked them up today at OA. Thanks again Jack!

Now I've done a fair amount of reading in the past 3 months, and trying to learn as much as I can about them. But I do have a few questions now that I have them in my tank.

First, they are fairly small, which is what I wanted. I really wanted to be able to watch them grow up, instead of buying them already almost full size. If you've been to OA, then you know the sizes of them. Both of them are fairly small (the biggest one being just a touch under 1").

My tank is a 38g, with about 25lbs of LR (I am planning on getting more, as soon as my stand is done). Up untill now, I have only had 1 802 PH for shaking up the water in my tank.

I figured before hand that the one PH wasn't enough, even after putting them in, so I went and picked up another 802. I have both on the back corners, facing towards the front center.

I did find this created almost TOO much turbulence (or maybe, that I'm just not use to it).

My question is, how much is too much? I know its a bit of a difficult question. Even with the one PH, the 2 fish are really having a "battle" it almost seems against the current. Or maybe they are not use to it? There didn't seem to be much flow in the tanks they were raised in. Would they go closed to the rocks, or under the rocks if it was too much? Are they maybe enjoying the newfound currents? After the lights went out today, they started to roam around the tank more.

Is it also normal for them to peck at eachother once in a while? I noticed them (or moreso the larger one) doing this for a few minutes here and there earlier today. Is that them 'playing'?

Sorry if most of my questions are stupid and total newb, but I'm just trying to learn as much as I can about these guys. They are way to cool, and want to make sure that their new home is a good one.

Thanks!
