Why are my zoas so small?
Another common cause of diminishing or undersized zoas is salinity flux. If the salinity of the tank is not kept stable, the zoa will release aminos and sugars to regulate internal osmotic balance. If you want to minimize wasting and maximize growth keep the salinity constant.
Do zoanthids like low flow?
Place zoanthid corals in an area of low-medium to medium-high flow. Too much flow may make it hard for the polyps to open. You will know your zoanthids are “happy” if they open and are fully extended without seeming to stretch too far upright.
How do you know if zoanthids are dying?
