Molly habitat and powerheads

[BBN]

Just curious. I have a 55g long mostly with mollies. I know some mollies live in the southeastern US and they can be acclimated to saltwater. So am I correct in assuming that mollies pretty much live in rivers and around the mouths of rivers that feed into the ocean? So would my aquarium benefit from having a powerhead in it to create a current for the mollies?

I moved a piece of sandstone today and a ton of piled up waste stirred up too so I may need ths to sir up the bottom. If a powerhead is OK I assume not a very strong one. Anyone have any recommendations as far as strength(gph)?

Thanks

BTW, off topic here, but after many years in saltwater I never thought I'd get addicted to freshwater again.:headbang2: Lovin my mollies. Six months ago I gave my whole 75g saltwater setup to my father n law who who never kept fish in his life and it's amazing how well that saltwater tank is prospering with corrals and all.

Mollies don't seem to do too well with a lot of current from what I've seen. I have a sailfin molly in my SW tank and it generally stays in lower flow areas.

So am I correct in assuming that mollies pretty much live in rivers and around the mouths of rivers that feed into the ocean?

They live in mostly calm brackishwater areas and also venture into full saltwater and freshwater.

This is from the wikipedia entry on them:
Sailfin mollies are most commonly observed as the shallow surface waters along the edges of marshes, lowland streams, ponds, swamps, estuaries and even ephemeral water bodies such as roadside ditches. Small to large aggregations of the species are most commonly found under floating vegetation or near structures in the water, minimizing their chances of being observed by potential predators.

So they're not a fish that lives in high current enviroments really.

OK thanks

I have 2 175gph powerheads in my 75gal brackish tank along with the canister filter, none of the mollies seem to take issue with it, they range all over the tank.
