questions re: new clownfish pair / MP40ws

[mike31154]

Give it time before getting overly concerned. When I added my first Maroon clownfish as a juvenile years ago, he (now she) didn't eat for a week & swam laps back & forth along the front glass all day. Beats me where he got the energy to keep up that behaviour for a week with no food, but didn't seem any worse for the wear. Simply started chowing down after the 7th, 8th day & eats almost anything now.

Clownfish in the wild won't last long without finding an anemone to call home, hence they are conditioned not to stray far from that area. So I'd guess the behaviour of your pair is not unusual. They've found a comfortable spot for the moment. It's a survival thing.

As far as flow, I have 3 MP40W ES VorTechs running in my 77 gallon, one at each end & one at the back in the middle. Not sure if you have the ES controllers, but I do & run the pumps in the ES Tidal Swell Mode (TSM) at around 80% max speed. I also use night mode & the pump on the back glass is configured to run at a slower speed even though it is a slave in the group of 3 pumps. The 77 is a narrow tank & flow from the back glass needs to be kept down to keep things manageable. TSM is similar to reefcrest mode & the pumps vary in speed throughout the day, until night mode kicks in. Suffice it to say that you shouldn't need to turn down your VorTechs in a 100 gal to make your clownfish feel at home. They should be more than able to handle your pumps running at 100%.
