I think it would be easy to decimate the population with just about any method, but I don't think you'll ever completely wipe them out if you have a good rock/sand base for them to live in. Since their bristles are mildly toxic and not a usual food source for most fish, it might be best to leave them out of the food smoothy.
The albinos, actually an albino male, het female, are a breeding project. Male should be ready to go next season and the female after that. I'll probably be picking up a dh sunglow pair and a dh snow pair over the next few months. I might end up in a few other morphs over time, but those 3 will be enough to keep me busy for a while.
