Care notes
Fruit Loops polyps are noticeably smaller than most zoas, so a single frag can look underwhelming at first. Give it a few months and it fills in into a dense, colorful carpet, which is how it looks best. The small heads pack tightly, and from a distance the colony reads as a mix of yellow and orange dots. The blue mouths only really show up close. Because the polyps sit so low and close together, detritus can settle between them. Moderate, shifting flow and an occasional blast from a turkey baster keep the colony clean. Its speed makes it a good candidate for an isolated rock or zoa island rather than the main reef.
⚠ Palytoxin safety
Like any zoanthid, Fruit Loops may contain palytoxin, so treat it as toxic. Wear gloves and eye protection when handling or fragging, and wash up afterward.
