I do take daily to weekly photos of everything. The blasto was fine for 8 or 9 days then on day 10 the baby head was skeleton and on day 11 the main head was fine and normal in afternoon and 4 hours later had a chunk of skeleton exposed and today (next day) it’s almost completely lost. I dipped last night with lugols alsoAny way to see if there’s something bacterial spreading? Take daily photos for a week of your other species to keep an eye on em.
