i'd be concerned about the heavy filtration on that tank; a 50g rated filter is pretty heavy-duty on a 10g tank.
Thatt's what i was thinking, i hope he can turn the flow down, as it must be like being in a storm.
As long as the fish are not struggling to swim, or being swirled round the tank.
corys can be kept with bettas no probs.
just because the water doesn't look agitated, doesn't mean there isn't a pretty strong current. a fish from still waters won't like the heavy movement. (especially if its got long flowing fins like a betta)
