Has anyone experience of Hatchet fish in high flow. I suspect it's a no no.
You can also use taller plants or hardscape to deflect some of the flow and create sheltered areas.
I kept Marbled Hatchets for a while, and they always used to <"sit in the flow from the spray bar">.Watched hatches sit in the full blast of a 3000 lph pump for the hell of it. Barely flicking a fin to maintain position, quite remarkable little creatures.
