The Indigo Hamlet is a commonly available fish which is a good addition to your aquarium because of its smaller size up to 2-4 inches. The Indigo Hamlet gets along well with almost everything and makes a good choice for a fish only tank. The Indigo Hamlet is considered safe for a reef tank as it does not bother any corals present in the tank. The Indigo Hamlet is hermaphrodite in nature and has both male and female sexual organs, so breeding has been done in captivity. The Indigo Hamlet flourishes well in home aquarium provided with basic water parameters such as 72-78 degrees Fahrenheit and pH of 8.1-8.4. With its beautiful coloration, temperament and general availability, the Indigo Hamlet makes a beautiful addition to any tank. The Indigo Hamlet should be kept in a tank not less than 30 gallons along with plenty of open spaces for swimming. The Indigo Hamlet requires plenty of caves and crevices so that it can hide when threatened. The Indigo Hamlet is a carnivorous fish and should be fed with meaty foods 2 to 3 times per day for its continued good health. The diet should include high quality pellets, frozen mysis shrimps, clams and squid, and other marine meaty items.
I bought one here last November and he survived a trip to MN in cold weather with a warmer pack. His bag water when opened was at 68 degree but after slow acclimation he did fine and has been swimming around my 40 gal Reef Tank since. He is now about 3 1/2 inches and a peaceful tank mate in my tank of 7 peaceful fish, i.e. 2 clowns, 3 pajama cardinals and a pygmy angel. Sometimes he will briefly chase the angel but does no harm. I have soft corals in my tank as well as hermit crabs, an arrow crab and 2 other crabs. He does not bother any of these. He adds color to the tank and sometimes it looks like he is looking at me with his big eyes.
