\"\"<\/a><\/p>\n

We started the week off with a popular freshwater pet, the Goldfish<\/a>, so I figured we could end the week learning about a popular saltwater pet, the Mandarin Fish. Unfortunately I have never had the pleasure of owning a saltwater fish, however, if my parents had entertained the idea of a saltwater aquarium, I would have been all over them to buy a Mandarin Fish. No offence to my pet Goldfish but the stunning coloration of the Mandarin Fish definitely makes them a much cooler pet. So once again, let’s grab our snorkelling gear and head to reefs in the Pacific Ocean to catch a glimpse of this fish in its natural environment.<\/p>\n

Uniquely Blue<\/h3>\n

Obviously the first thing we notice with this amazing fish is their bright colours. Did you know that the Mandarin Fish is one of only two fish that has a blue coloration due to a cellular pigment. That’s right, only this fish and a closely related species, the Psychedelic Mandarin, use cyanophores to make their spectacular blue colouring. The boring blue in other fish is created from light interference as a result of flat, thin, reflecting purine crystals. Sure it may not sound like that big of a deal but it does make the Mandarin Fish unique….and it does create an amazing blue colour.<\/p>\n

Small and Hidden<\/h3>\n

As mentioned, you will find these beautiful fish hanging around reefs, specifically sheltered and in-shore reefs, in the Pacific Ocean around the Philippines and Australia. Although they are quite common throughout their range you may have a tough time spotting the Mandarin Fish in their natural environment. Wait a minute! There is no way this fish wouldn’t stand out, right? That is what you would think but they are rather small with an average size of 6 cm (2.3″) and they are usually hanging out on the ocean floor. Therefore, you had better keep your eyes open while swimming through the reefs of the Pacific Ocean.<\/p>\n

Picky Eater<\/h3>\n

Although the Mandarin Fish is popular among the pet trade, they are actually a difficult fish to keep in an aquarium. You see, this particular fish loves its diet of copepods, worms, fish eggs and gastropods. I mean, who could blame them, this diet sounds delicious. Their particular and diverse diet is difficult to mimic in a controlled setting, which tends to lead to the death of the pet Mandarin Fish. I recommend catering to their strict dietary needs if you plan on keeping your new pet for any amount of time.<\/p>\n","protected":false},"excerpt":{"rendered":"
