Gold Ring Danio (Danio tinwini)

Gold Ring Danios are relatively popular in the aquarium hobby. These Danios are good looking, peaceful, fairly active and quite hardy, making them suitable for the beginner aquarist. In addition, these Danios make excellent members of a community aquarium with similarly-sized, temperate species.

Ideal tankmates for Gold Rig Danios could include small non-aggressive fish such as other Danio species, Dwarf Barbs, Most Tetras and livebearers. You can also house these Danios with Gouramis, Dwarf Cichlids, Loaches and Catfish. However, it would be better if you avoided much larger fish species as they may see these Danios as a snack as well as slow-moving species as they may feel intimidated. It is also recommended that you avoid fish with intricate finnage as these Danios may initially nip at their fins.

Gold Ring Danios are shoaling fish in nature; therefore, it would be best to keep them in groups of at least six individuals, preferably more. Keeping these Danios in larger groups will make your fish feel more comfortable and will give your aquarium a more natural-looking display.

It would benefit your Danios if you maintained them in a well-planted aquarium or an aquarium designed to mimic a flowing stream or river. The substrate can be made up of gravel, different sized rocks or a few large smooth boulders. You can use additional powerheads or filter outlets to provide flow; however, you should avoid swift currents because Danios usually occupy calmer waters in the wild. It would also be good for your Danios if you added some driftwood roots and branches and some hardy aquatic plants such as Anubias, Microsorum or Bolbitis.

A tight-fitting lid will also be required on your aquarium as Danios are exceptional jumpers and can fit through the smallest gaps.

Gold Ring Danios are relatively small and have torpedo-shaped bodies.

Their body pattern consists of four horizontal, rather large spotted lines over a golden bar. These lines change to solid stripes once they reach the anal fin. The stripes begin after the operculum and, from there, continue over the entire body, including the caudal fin. In addition, a large white blotch can be seen at the anterior part of the belly. Dorsally, the fish are silvery-grey. The fins are completely translucent except for the blue to black dots. These dots are not present on the pectoral fins.

Natural Habitat

Gold Ring Danios are endemic to the Mogaung Chaung, a tributary of the Irrawaddy River in the Myitkyina District in Kachin State, northern Myanmar in Asia. These Danios inhabit moderately flowing, well-oxygenated streams and minor rivers surrounded by subtropical and tropical evergreen rainforest rather than monsoon forest.

What to feed the Gold Ring Danio

Gold Ring Danios are unfussy in the aquarium. However, a high quality dried product should be used as the staple diet. Still, it would help if you supplemented this with frequent meals of frozen, live and freeze-dried foods such as mosquito larvae, brine shrimp, bloodworm, daphnia and cyclops, as this will allow your fish to reveal their best colours and condition.

How to sex the Gold Ring Danio

It is relatively straightforward to differentiate between the female and male Gold Ring Danios. The males are usually smaller, slimmer and have more intense colouring than females. In contrast, females are somewhat larger, have fuller bodies, especially when carrying eggs and are much duller than males.

How to breed the Gold Ring Danio

When your Gold Ring Danios are in perfect condition, they will spawn often, and in a heavily-planted, mature aquarium, small numbers of fry may start to appear without intervening. However, if you would like to improve the yield of babies, a slightly more controlled approach will be required.

You can condition your adult group together, but you should also set up a separate breeding tank and half-fill it with mature water. It would be best to fill much of the available space with suitable spawning mediums such as spawning mops or java moss, or you can place either a mesh or marbles on the bottom of the tank where the eggs can fall through to hide the eggs.

Their water will need to be somewhat acidic to neutral with a temperature towards the higher end of the scale. You may also add an internal power filter making sure that you position it so that the flow is directed down the tank's entire length.

Once you have conditioned the adult fish and the females appear to be full of eggs, you should then introduce one or two pairs into the breeding tank.

To begin the spawning process, you should add small amounts of cool water every couple of hours so that the tank is gradually topped up or perform a significant water change in the evening. Providing your Danios with small amounts of live and frozen food can also trigger spawning. Several spawning events will probably occur before a female has run out of eggs.

The adults will most likely consume any eggs they come across, so it would be best to remove the adults once any are noticed. At this point, it is advisable to switch the power filter to a mature sponge filter to avoid the fry being sucked into it.

The Incubation period is temperature-dependant to an extent but typically takes between 24 to 36 hours. The fry will then become free-swimming a few days after that. Therefore, it would be most beneficial if you initially fed your fry on newly hatched brine shrimp or microworms.
