I used to think it was my flame angel nipping at me deresa but last night I saw my bi-color blenny bugging one of my croceas. I was thinking maybe because the mantle has some brown in it? The deresa is doing fine & it seems that nobody is messing with it anymore. But now my crocea is the new target. I'm having trouble deciding which to remove. But I like them both. A better solution would be to stop the blenny. Any ideas?
