Small algae eating fish?

I read a little about it and it says they like a river type setup/fast flowin water. Im keepin fish that dont really do good with currents :(
 
I suppliment mine with Hikari(sp) algae wafers which they love. The better fed they are the less territorial the dominant male is, they have a pecking order for sure.

I don't have a ton of current in my tank, 40gal with an XP2, spray bar mounted along the short side meaning the current runs right to left . . . anyway just offering some interesting alternates, I have found both of these to be curious, hardy and entertaining species.
