Not a fair statement. I keep loads of wrasses. 8-10 in tank last time i added Nudi’s. They’re not going make a difference. I saw one or two taste the nudi’s then quickly spit em out.
Interesting, I have never heard that before. In fact I kept away from adding nudis in my last tank because I had wrasses, and the nudis are spendy. My wrasses constantly pick off hermits and snails, have to add new hermits every 2-3 months and snails a few times a year. I have tried 2 fighting conches both were gone within the first 24 hours.
