Active management can probably work but it's like living on the edge with no safety margin. You would probably need a large Tank with lower-than-average Fish Load and a large UV setup for Parasite Eradication with adequate turnover and inlet water pulled from the Tank itself.
The main problem as I see it is a single stressor event could Trigger an Outbreak. Events like a Power Outage, Equipment Failure, adding a new Fish. etc.
One last thing is moving water. Not many stagnant areas that can give them a hag out area until a fish swims in that area using it as a sleep spot for the evening.
