As much as I do not like zoas, utter chaos and blue Hornets are the best zoas in my eyes.
Beauty.
I think typical zoa care.
Bottom placment, medium to low flow, medium to low light..but by all mean am no expert. Last time I kept zoas was 10 years ago..
If you put them in high flow you will get smaller heads more often and brighter colors, lower flow will give you large polyps. Which weighs more I don't know.
Mine grow like weeds for some reason. They have out competed almost every polyp of every other zoa/paly on the rock they are on. Honestly couldn’t tell you the secret tho. They are in lower light med flow.
