All about the Sun Coral

Here we are learning all about the Sun Coral, also known as the Tubastaea, Yellow Cup, or Sun polyps corals.

Prices: $50 

Care Level: these are tough to take care of, especially for newcomers. They have a very picky lifestyle to thrive in the tank.

Water Parameters

  • Temperature: 72-878 F
  • dKH: 8-12
  • pH: 8.1-8.4
  • Salinity: 1.023-1.025

It's the bright yellow and bright orange on them that's eye-catching. Make sure that the levels are in check with lots of calcium and magnesium to keep their skeleton strong.


They are non-photosynthetic corals. So they do not live off the light. They need to be spot feed. they require constant feeding throughout the data, like brine shrimp, micro-plankton, and other reef food. 

You need to feed them more than two times a day. It's not that they need a lot, they just eat constantly throughout the day.

They are like Anthias, where you feed them multiple times a day.


They are aqua-cultured. Originally they were from the indo-pacific areas. So you could have found them in the great barrier reefs and all along that island.


This coral would not be stinging anything, but it can be stung. So keep them away from venomous corals.


Under hanging, in the caves, and in other dark spots in the tank. They thrive in this section. So keep them at the bottom.


You don't want any bacteria on their skin. Therefore you need a strong current to keep your skin clean. However, on the same note, you do want to shut the power heads. So technically, they don't require any lighting. But they look great under high-powered LEDs.


They can be dragged in between the head. Their exoskeleton is strong. So most people with people need tools to cut them clean. Since they grow slowly, you would not see a head every month. Be patient with them. They will grow. 

When acclimating them, keep them longer than a typical coral because they are sensitive. Also, grade them from the bottom and not the polyp.
