The Aquacultured Green Bubble Coral Physogyra sp. is easy to care for and shows itself off well in any reef aquarium. Needing only gentle water movement and low to moderate light, this is an easy LPS with very few demands. These inflated structures pillow outward from a solid, stony skeleton and prefer to be placed in lower flow environments. This is a tough species, great for entry level coral enthusiasts because it prefers less direct flow and can tolerate a range of lighting and placement options inside the aquarium. Make sure to keep some distance between this species and other corals, as the Bubble Coral has elongated sweeper tentacles that can be aggressive
Difficulty It is easy to maintain in the reef aquarium, which makes it an excellent candidate for the beginning through expert reef aquarist.
Aggressiveness Be cautious, while the bubble does not have toxins, they have the feeding tentacles which are capable of delivering a sting to any coral invading its space.
Does best with gentle water movement.
Can do well under lower lighting levels. They can do well under stronger lighting too, as long as they are acclimated to it over a period of time. T5's, Metal Halides, or LED's can all grow Tongue Coral when the proper levels are provided. We recommend a 14-20K color spectrum for best coloration.
A well-feed live rock/reef environment is what is needed for any Bubble Coral, along with some fish for organic matter production.
Diet and Feeding
Best to feed in the evening when the feeder tentacles are out. Feed mysis, rotifers, enriched brine shrimp, Cyclopeeze and other similar sized meaty foods. Try to not feed large pieces since it makes it difficult for the animal to digest such foods and often results in them regurgitating late at night. When this happens, they are not benefiting from the feeding and it can lead to eventual starvation.
It is best to feed them well and keep them happy, then they will form buds which can be harvested and produce quite a few colonies a year! Just be patient. The larger your coral gets, the more "babies" it will give you.
