Fast Current?

[MadCatter]

What sorts of brackish fish would do well with a faster water currents? Is it okay to have two powerheads in a 10 gallon? They're small, but we'd like to make sure there is not too strong of a current present. Thanks for the help/suggestions!

10 gallons sounds quite small ( are you going to keep Gobies )...

Bumblebee gobies would work very well providing the current isnt too strong, as they have fused pelvic fins which act like a suction cup which are designed so that they can attach themselves to rocks in the wild where they often live in fast flowing waters (i think).

While I'd take issue with the word "designed" -- "evolved" is a better word -- yep, this is exactly right. The goby-group of families appear to have evolved in streams and then secondarily invaded the sea, where the same trick works very well in tidal waters, on coral reefs, etc where there are strong currents. That said, don't go bananas. If the gobies are having obvious problems staying in one place, then remove a powerhead. Also, too much turbulance (bubbles/churning) at the surface of the tank can supersaturate the water with atmospheric gases, and these can cause things like pop-eye because bubbles of gas get trapped within the tissues of the fish. This is very, very rare in aquaria, but it can happen.

Thanks a bunch

Just curious, why do you have 2 powerheads in your tank? The flow from a regular HOB filter is more the adequate. If it's because your using a UGF you should consider a different filtration method. UGF's can only be used with gravel and bumble bees really should have a sand substrate.

It's actually my boyfriends tank that I've agreed to take a part in raising up. We're just thinking of what we can do with it now is all, haven't made a real plan yet. He got a bunch of stuff free, and the two powerheads just came along (they're both very small.. I believe one was for small bodies of terrarium water? not sure, I can check next time I'm over there).

Fish keeping is a lifelong hobby for me, but I've only recently had a brackish tank (with only a f8 puffer), all other tanks have been fresh. The hobby is completely new to him, and so this task is an adventure for the both of us. Our plan is well.. to make a plan, budget (we're both in college, and saving up to go to out of state school next year), and then see it through.
