I’ve read it. Maybe you read it again. I answered what you asked. There is no antibiotics without killing good stuff, it’s how it works.
You said you want to manage ich. You gotta go slow if that’s your goal.
Not a bad idea, but most of what you named aren’t really being propagated captively. Scollies and acanthos are possible, sure, but I dont see it being done. Not sure anyone is breeding clams in the club either.
The skeleton seems to have more texture to it if that makes sense. Maybe I just haven’t noticed, but the spongodes im used to seems more smooth skeleton
Looks like what I have seen called montipora spongodes. The fact I’ve seen a coral that looks like that called something more than once means very little in reality tho lol
