Zoa eating Nudibranchs

[ScubaSteve]

I've done battle with these bastards in the past. The problem isn't the nudis, you can pick them off and fish can get them. It's the eggs that are the nightmare. I recommend taking the colonies out of the tank and spending time picking the eggs and nudis off. They can do some serious damage to your colonies before a fish could make a dent in the population.
