No, he basically avoids it. My trio of the red lizard whiptails spend a lot of time at that end of the tank, but this may be related as much to feeding as current, since that is where the sinking foods are dropped.
On the corys, most actually do not prefer significant flow. My 30+ remain well out of the flow from the filter, again except when feeding. Some species occur in moving streams, but these are not raging torrents. And they may remain in the side shallows more where the flow is less than in the main channel.
Interestingly, my Farlowella have spawned dozens of times over the past 2 years, and they always use the glass below the spray bar. This is rather interesting, since all three of them tend to avoid this area otherwise, remaining at the opposite end or the centre.
