tetra current?

My neons stay away from the current in my tank but theres plenty of places where the water isn't moving much

but my red-eye tetras (about 1.5") love swimming against it - They go really slowly "upsteam" then turn and shoot back down the other way - and with 6 of them its great to watch.
 
What is strong current? Are we talking a powerhead?

if the filter is causing a decent amount of current, then some floating plants will provide some shelter on the other side of the tank.
