Halichoeres chrysus: factsheet, nutrition and maintenance tips. What no one will tell you about banana fish but which will come in handy in managing the marine aquarium.
Please note: when you introduce it inaquarium, L'Helichoeres chrysusit becomes silted up and a few days may pass before its appearance on the surface.
If you believe yourHelichoeres chrysusbe "disappeared from the aquarium", Quiet, for the stress and fear he went hunting for a refuge, a small ravine or ... if your bed of sand is thick enough, it is" covered up ".
I'll tell you about this habit right away for two reasons: to host thebanana fish Helichoeres chrysusyou must have fine sand and above all you must be able to tolerate the numbness of the water that your eating habits cause.
In short, theHelichoeres chrysus it is a very beautiful fish, which adapts to small aquariums ... but moving the sand makes the water numb. This effect is less dramatic in large aquariums, in quiet aquariums, full of rock shelters and with movement pumps positioned at the top. I'll come back to the topic later!
It is a fish that is easily found on the market, it also has apriceaccessible but, as I often explain, thepricethe dealer does it! So I can tell you I paid mineHelichoeres chrysusonly 15 euros (bought from Moby Dick in Nola, in the province of Naples, during an offer period) but I can also tell you that I saw it at double the price at small retailers.
Helichoeres chrysus: card
Common name: banana fish, canary wrasse, wrasse canary fish, yellow damsel, canary damsel, yellow coris.
Origins: Eastern Indian Ocean, in particular Christmas Islands. Western Pacific Ocean, especially Southern Japan and New South Wales.
Size: 12 cm
Natural habitat: it lives among the coral rubble, on the edges of the cliffs. Typically new at depths between 15 and 60 meters.
Diet: carnivore, its main diet, in nature, is linked to small crustaceans or benthic fauna that it finds among the sandy bottoms and rubble.
Description: both male and female specimens have an elongated yellow body. Adult males have a black spot on the anterior side of the dorsal fin. Adult females have a black spot bordered with yellow in the middle of the dorsal fin and a very small black spot on the caudal fin.
Here's how to tell the male from the female. From direct experience I say that most of the specimens on the market are females. It is equally important to specify that the number of spots and their position on the body vary not only according to sex but also according to the age of the specimen, which is why I stressed "in the adult male" and in the "adult female" .
Helichoeres chrysus in the aquarium
The ideal aquarium should have a very thick bed of fine sand (grain size 0.2 - 2 mm), about 10 cm. A very thick sand bed allows the development of a particular fauna that is not found in aquariums with thinner sandy substrates. A high thickness has two advantages forhelichoeres chrysus, on the one hand, it autonomously provides for its ownsupplyand on the other hand it allows it to be covered up.
L'helichoeres chrysus in the aquariumit will spend most of its time sifting through the tank for small invertebrates living in the rocks and on the bottom. If you have any annoyingspaghetti worms or other polychaetes, these little onesyellow fishit could help you eliminate them by feeding on them. In the absence of small invertebrates or crustaceans (such as copepods) it could also annoy small ornamental shrimps or snails (but only if small in size).
L'Does Helichoeres chrysus numb the water?
Normally it does so only in the first period of introduction into the tank. This fish, in fact, only gets covered up in the sand when scared, annoyed or ... in the evening, to sleep if it cannot find a safer refuge among your rocks.
By moving the sand, the fish causes not only an aesthetic discomfort but also damage to the corals. This is why it is important to leave the fish calm and observe its behavior after an initial phase of adaptation in your aquarium.
Helichoeres chrysus: feeding
I have already described the diet in its natural habitat. The well mature tanks with a very double sand bed can guarantee a good sustenance for this fish, however, if introduced in a nano reef or in a not very populated tank (devoid of benthic fauna) you will need to administer mysis, copepods and other foods (including frozen) to be administered twice a day.
Unlike fish of the Pseudochromis genus which fear being very aggressive with other tank mates, thehelichoeres it is a peaceful fish, so if not stressed it will not annoy the other specimens already present in the tank.
Please note: a female is shown in the photo above. In the photo in the center of the article aHelichoeres chrysusmale. It is recommended to introduce only one male per tank.
