Peacock gudgeon or peacock goby (Tateurndina ocellicauda) has smart and vivid coloring, it is absolutely unaggressive and not demanding fish. Isn’t it a perfect choice for a community tank? Unfortunately, it is not quite renowned among aquarists. Maybe this happened due to the lack of information about it. So, let’s fill this gap.
Habitat in the wild
This good-looking small fish actually is not a carp gudgeon, it is a representative of Eleotridae family. Species from this family don’t have coalesced pectoral fins like those of true carp gudgeons.
This fish kind is one of the smallest and the most attractive among the family representatives and it is a perfect dweller for a tank with live tank plants.
Tateurndina ocellicauda inhabits in shallow slow or lentic waters of rivers, streams and ponds in the South-East of Papua New Guinea island. The fish dwells in lowland streams, ponds and rivers mainly in the East of the island.
More often the fish is encountered in tropical forest ponds where it swims in shallow waters.
Peacock goby (Tateurndina ocellicauda) is a very colorful freshwater carp gudgeon. Its body is bluish and silvery with pink, yellow and black marks along the body and fins.
In the wild the fish males grow to be up to 7,5 cm (3 in) long and the females become up to 5 cm (2 in) long. In captivity the fish doesn’t grow that large. Its lifespan is about 5 years.
Peacock goby catches the eye with its vivid coloring: its back is brown, there are shiny red lateral dotted stripes along the fish azure sides and its abdomen is yellow (the females have it more brightly yellow, especially during the spawning period).
There is a blurred black spot on the fish body where the tail begins. Dorsal, tail and anal fins are light blue with red spots.
Difficulties in keeping
The fish is not large, calm, not aggressive – in general it is almost a perfect choice for those, who like bright and small fishes.
The only drawback of the fish (except that it tends to eat only live food) is its liability to infectious diseases – this is a usual reason of the fish death in a tank.
The fish that is prone to various diseases are first of all those imported from South-East Asia. Their immune system and health were sapped due to long transportation.
However, the fish that was bred in a tank has good health and can live up to 4-5 years long.
Care and keeping in a tank
|Scientific Name||Tateurndina ocellicauda|
|Common Name||Peacock gudgeon, peacock goby|
|Tank size||40 liters (10 US gallons) and more|
|Temperature||72°F-78°F (22 to 26 °С)|
|Size||up to 7,5 cm (3 in)|
A small tank of 40 liters (10 US gallons) capacity will do for a couple of fish. Peacock gudgeon feels safe and comfortable among large number of floating plants.
Using dark tank bottom substrate will help the fish to demonstrate maximum of its beauty. You can use coarse grained sand or small gravels up to 5 mm as the bottom substrate.
Tank lighting shouldn’t be bright – dim light is more preferable for the fish. The water flow should be minimal. It is recommended to perform water renew once in a week. Though the fish is not demanding, still it is better to provide water filtration.
The fish males are not aggressive, but they may demonstrate territory dependence, that’s why they require large number of various shelters. You can make them from snags, various caves and etc. Rivalry between the male species is also not aggressive.
They may strike intimidating poses or suddenly attack their rival, but still all these things are done to scare him off, not to hurt.
Surprisingly, in tanks like this the fish will be unobservable. In tanks without any decorations and plants, the fish usually sticks together around any small shelter they find and swim very little.
Though peacock gudgeon likes clean water, but it will feel uncomfortable, if the water flow in a tank is too strong. The fish jumps well, therefore make sure that there are no gaps around the tank lid.
The only drawback of this fish kind is its taste for live food. Quite often the fish ignores dry food (though sometimes you may succeed to train them to eat small pellets). As for small sized frozen food (cyclops, coretra, bloodworm) the fish isn’t very happy to eat it.
As for the frozen brine shrimp – it’s not reasonable to feed the fish with it, because the fish prefers gobble up the food not to mouth its prey.
If you (just like me) regularly feed your fish with artificial food, then the links will be very helpful for you – HIKARI Micro Pellets, API Fish Food Pellets, Fluval Bug Bites, Zoo Med Spirulina. I know what it’s like when you pet fish die because of low quality food or get ill due to infection ingress into the tank with live food. I myself give some of this food to my pets and as for the rest I’ve heard and read lots of good reviews. Yet, all of the food is of high quality and it is the best one for this fish kind as well as it keeps the tank water clean.
Tateurndina ocellicauda is quite calm and peaceful fish that won’t disturb its tankmates even of smaller size. This is the reason why this fish is an excellent dweller of a community tank.
You should take into account the fact that peacock gudgeon is very sedate and deliberate in manner when feeding tank dwellers.
Make sure that the fish gets enough food if there are some fast and active fishes in a tank. Other fish species that inhabit in Papua New Guinea island will be perfect tankmates for Tateurndina ocellicauda.
Both males and females of this kind are nicely and brightly colored. Both of them have a black spot where their tail fin begins.
Anal and dorsal fins of the male fish have bright yellow edges and those of the females have black edges. Males are larger, brighter colored, their head is bigger with high forehead. Snipy females have receding forehead.
Abdominal fins of the fish are colorless as a rule, but during the mating game the females have them black colored and the males have them brown with bluish tint.
The fish breeds in couples. It is better to put the fish couple into a separate spawning tank which must have shelters since it is where the female fish lays eggs. It is easy to see the female fish that is ready to spawn – it has rounded, large and high yellow colored abdomen.
You may raise the tank water temperature at 1-2 oC in comparison with the community tank. During the mating game the abdominal fins of both fish change their color – male’s fins become dark brown and the female’s ones – black.
The female lays from 50 to 200 eggs about 1 mm in diameter. After the spawning is over you should take the female fish away from the spawning tank.
The male fish takes care of their offspring. Male fishes are very caring parents and they stay in the cave all the time. They don’t leave it even to eat.
All this time the male fish actively waves its fins fanning the eggs and this way saturating them with oxygen. In 6-10 days (depending on the tank water temperature) the transparent larvae about 2-3 mm long appears.
Once this happens you should remove the male fish from the tank as well.
In 2-4 days the juveniles start to swim. You should start feeding them with infusorian, brine shrimp nauplii, rotifer.
Provided with good tank conditions peacock gudgeon juveniles grow about 1 cm longer each month. Approximately in a month the juveniles will have a black spot near their tail fin.
However, they will get complete coloring of the adult fish only in 4 months. Peacock gudgeon becomes reproductive at the age of 6-8 month.
