questions re: new clownfish pair / MP40ws

[habs247]

hey everyone,

my first tank has completed its cycle and after five long weeks i added my first fish to the tank today, a pair of false percs.

having had no experience with these fish, and it being my first marine tank and all, i turn to you guys to make sure i don't make any avoidable mistakes.

first question: the pair seem to be swimming in one spot primarily - front of the tank, middle, near the sand bed. they appear to be fighting the current and have pretty much stayed in the same spot all day (all though they have had moments exploring the ends of the tank, both together and separate). but mostly they stay in one spot, and as night falls, they're still doing the same kind of thing - just "fighting" the current, hanging there...is this behaviour normal?

second question: related to my first - perhaps the current is too strong in my tank? it's a 100g (48x24x20) that has two MP40s for flow, running at 70% reefcrest. when i turn the pumps off, they seem to be a bit more exploratory, but i imagine i'll normally have to keep these pumps on as the tank matures. should i be turning them down?

any advice is appreciated. thanks in advance guys.
