Colt Coral are fast growing and easy to keep in the home aquarium. They are easily distinguished from Leather Corals by their slimy texture which is similar to a wet bar of soap. They will sway back and forth in the currents beautifully as they filter food from the water.
Rinse: This coral will slime during shipping. Make sure to rinse it off in saltwater before placing it in your display aquarium.
Placement: Mount the the Colt Coral on an exposed rock in the bottom two-thirds of the aquarium. Leave several inches around the Colt Coral as it can sting and harm other corals it touches, especially Leather Corals
Feeding: Although symbiotic algae called zooxanthellae hosted within them supply most of their nutritional requirements through photosynthesis, they do require supplemental feedings of phytoplankton and marine snow.
Lighting & Flow Requirements:
The Colt Coral requires moderate water flow and low to moderate lighting (PAR 150-300). T5's, Metal Halides, or LED's can all grow Colt Corals when the proper PAR levels are provided. We recommend a 14-20K color spectrum for best coloration.
Care Level: Easy
Lighting Requirements: Moderate (PAR 150-300)
Water Flow: Moderate
Range: Fiji, Indo Pacific
Water Conditions: 75-80° F; sg 1.024-1.026 (1.025 is ideal); pH 8.1-8.4 Ca 420-440 ppm, Alk 8-9.5 dKH, Mg 1260-1350, Nitrates <10ppm, Phosphates, < .10ppm
Water Chemistry: Providing additions of iodine will help the Colt Coral grow. Most good salt mixes will provide enough iodine through water changes. It is important that proper calcium (420-440 ppm), alkalinity (8-9.5 dkh - run it 7-8 if you are carbon dosing) , and magnesium levels (1260-1350 ppm) are maintained. Raising magnesium levels gradually up to 1400-1600 ppm can help to combat algae outbreaks, just keep CA and Alk in line as you raise the Mg. Nitrates should be below 10 ppm and phosphates should be below .10 ppm. We recommend doing a water change when Nitrate levels rise to 10 ppm. It is important to replace your phosphate media when phosphates rise to .10 ppm. Media Reactors make the most efficient use of your phosphate media by fluidizing it.
Dosing: Vivid Aquariums uses and recommends dosing pumps to automate the dosing of additives and keep your levels more constant. A dosing pump can alleviate the chore of manually dosing your aquarium with Ca, Alk, & Mg 2,3, or 4 times per week and will benefit your aquarium by keeping your levels constant through frequent small additions of Ca, Alk, & Mg. Our tanks all progressed when we switched from 3 manual dosings per week to 70 automatic dosings per week and we got a lot more work done.
