Hi! Still new to the hobby and I’ve done a lot of research but I haven’t been able pinpoint these things as there are people saying different things so I figured I’d ask you all more experienced people. The first thing are small flower looking things appearing throughout my coral & on the rockscape all over. The 2nd thing are long white tubular things that are everywhere on my rockscape. What are they? Are they good/bad? Pros/cons. if they’re bad, can I manually remove them? Are they hitchkickers or do they just grow? I appreciate all the assistance and knowledge!! Thank you
