I have mine in my 75g sump and some days I have it blasting with a 3200gph powerhead and it doesn't mind it but at the same time it doesn't move around like it does with a bit less flow. It doesn't hide from the flow though so that's what makes me think it doesn't mind it.
From what I've learned, Red Wolves are indigenous to bogs/backwaters...other wolves are more stream/river dwellers and would therefore do better with a bit of current in their environment. Red's don't appear to need it that much.
