Zia need moderate light and water flow with placement being important. Light intensity should be closer to medium for their production of zooxanthellae which gives them energy and coloration
Also add iodide to water periodically which they convert to iodine which is also needed
Assure you have no pests around them such as little bugs, spiders nudibranch or worms
