Torch Coral/Euphyllia glabrescens Type: LPS Origin: Indo-Pacific, Australia, Solomon Islands Aquarium Needs - Lighting: Moderate/high Water Quality: high Current: low/moderate Temperament: aggressive Supplemental Feeding: small, meaty items Frag Difficulty: Easy Personal Observations - My personal favorite of my corals! Very interactive. At feeding you can see it sway out it's tentacles is an effort to capture food. Tentacles on mine can extend to about 6-8 inches when its at its "happiest", with a lot of movement. Moves a lot more when its in lower flow areas (I keep mine towards the bottom of the tank sheltered by some rocks). Make sure you have powerful enough lighting to sustain it if you plan on doing the same. Important to note that you must leave ample room between the torch and other corals or sessile inverts, as its tentacles can reach out quite far and sting or gather/capture. Also, very good water quality indicator. I can see a definite difference in its happiness with just a change in nitrates such as going from 0 to 5. Clowns can attempt to host it (mine did). My torch was not very happy with it, but have heard of some that will allow it. I supplement mine with Pacifica Krill once a week, but they will also take small pieces of silversides, shrimp, etc.
