Thanks in advance!
Recently some of my Zoas started shriveling and closing up. Parameters are all fine, so I started inspecting closely and found a few different things that could be causing it. Would greatly appreciate ID & Treatment advice🙏🏽

1️⃣ I believe to be Hydroids. I see 1-2 on every Zoa frag.

2️⃣ Boring Spionid Worm?? These guys look like tiny tubes with clear filament like tentacles coming out. Pretty sure they’re Boring Spionid Worms. I’ve tried multiple dips and nothing seems to faze them.

3️⃣ I was told the Crawlers were "Zoa Spiders" They are microscopic & l only find them on the stock/frag plug. Zoa spiders are usually in the mouth area. I did a Revive dip which didn't help, I then tried an lodine dip which eliminated them completely off the frags but, later repopulated since they're in the sand bed aswell. Since they don’t seem to cause visible damage, I’ve been assuming they’re harmless for now😅 they move pretty slow, they do not dart around like pods.

4️⃣ Clear Hair Like film that forms around some polyps. I’ve dealt with this before and used a high ratio of hydrogen peroxide, which removed it but burnt the Zoa patterns ( I have Speckled Strats now lol..) Not sure if it’s bacterial, hydroid, or something else entirely.

I forgot to mention, I also started noticing some zoa pox. What could this mean? All happened in a span of 2 weeks. Everything was opened growing & thriving…
