Eleotris carpet / Peacock goby (Tateurndina ocellicauda) Nichols / Nichols, 1955

Family Golovoshkovye (Eleotridae).

Carpet eleotris, is the only species belonging to the genus Tateurndina, and in fact is not a bull, but is a member of the Eleotridae family. It is one of the smallest and most attractive species of the family.

Papua New Guinea.

They inhabit lowland streams, ponds and rivers mainly in the eastern part of the island. It is most often found in the waters of tropical forests, where it swims in free flocks.

Eleotris carpet (Tateurndina ocellicauda) is a very colorful little freshwater goby. The body is bluish-silver with pink, yellow and black markings along the body and fins.

Both sexes of this species have a bright turquoise color with a lot of red broken lines and dots. They have two dorsal fins (front – shorter). A longer dorsal fin of the same size as the anal fin.

The female has a black line at the edges of both the anal and dorsal fins. On the contrary, the male has bright yellow edges.

Both sexes have a black spot at the base of the caudal fin (hence the name, Peacock Bull). Although both stomachs are yellow, the female has a more pronounced yellow color, especially in the state of reproduction. The most noticeable difference is the shape of their head.

The female has a pointed head, and the male has a humped head and a much stronger, angry-looking jaw. Sometimes, depending on the angle of view, the male’s eye will reflect a red color.

This is not observed in females.

Both males and females of this species are equally beautifully colored.

Males grow to 6-7 cm, while females remain smaller, about 4-5 cm.

Carpet eleotris (Tateurndina ocellicauda) lives in a pair or in a harem. If this last option is preferred, a male with two or three females is recommended.

A little territorial with its own look, but suitable for many aquarium communities of small, peaceful fish. Ideal neighbors are other species from Papua New Guinea, such as Popondetta sp.; Tetras, Rasbory, Corridors and any other small peaceful species are also suitable.

Make sure you have enough space in your tank if you are going to keep it with other territorial species, such as dwarf cichlids.

Peacock gobies can be kept without problems in small groups with a predominance of females. They will quarrel among themselves, but this is almost always limited to a flash of aggression, which makes observing them more interesting than if you were just a couple.

The size of the aquarium 45x30x30 cm – from 40 liters is great for a pair of adult fish.

Eleotris carpet prefers soft, slightly acidic water and plenty of shelters. The use of dark substrate and floating vegetation will help them feel more confident and demonstrate their best color.

They also need a large number of shelters, so you need more submerged snags, stones and places with a dense planting of aquatic vegetation. Paradoxically, but with this design they will be much more invisible. In the “bare” aquariums, they usually huddle around any accessible small shelter and move much less.

Although they like very clean water, they will not feel comfortable if there is a strong movement of water in the reservoir. These bulls are also good jumpers, so make sure there are no gaps around the aquarium lid.

Temperature: 22-27 ° C
PH: 6.5-7.5
Stiffness: 5-10 ° DH

Replacement of water by 20% should be done weekly.

Usually take dry food, but prefer small live and frozen, such as bloodworm, pipeker, koretra, daphnia, artemia, etc. The fish will show a much better color and will move to a spawning state much faster with such a diet.

The mature male, as a rule, is brighter (especially in the spawning period), a pronounced occipital hump develops and is slightly larger than the female. Females have a yellowish color on the abdomen, which males do not have. When the fish are younger, the gender can be determined by looking at the anal fins.

Most females have a dark edging that runs along the length of the outer edge of this fin, while most males do not have it.

Peacock goby (Tateurndina ocellicauda) is easily divorced under suitable conditions. Fish tend to spawn in caves, so their provision is very important. Small length plastic tubes are well suited, as they can be easily removed by closing each end.

Bushes of living plants are also useful to provide additional shelter for fish.

To get a breeding pair (producers), it is best to buy a group of 6-8 young fish and allow them to naturally mate. Provide the group with good nutrition, live and frozen food, change 25% of the water weekly, and you will observe spawning behavior that does not take long.

When the fish are ready to spawn, the belly of the females will become noticeably rounded, and the males will be located at the entrances to the selected caves. Whenever the female approaches the male’s cave, he will tremble and smooth his fins trying to lure her into the cave.

Sometimes he even uses force, pushing the female towards the cave entrance.

If the male succeeds, the female will swim into the cave and set aside from 30 to 200 eggs, usually from above. Caviar is attached with small sticky threads. As soon as the female completes the laying, she is driven away by the male, who now assumes all the duties of caring for the deferred caviar.

As a rule, he almost always takes care of the eggs, fanning them with his fins so that the water around them is well saturated with oxygen. If you plan to grow fry in the same aquarium, you can remove other fish, as they will eat caviar if they can get to it.

The larvae hatch in about 24-48 hours, and the male completely stops caring for the brood from that moment on. Now the fry need a separate aquarium or they will usually be eaten.

They begin to swim freely for another 2-4 days and they are very easy to feed, being large enough, they can immediately take Nauplii Artemia, microworms, and so on.

Growth is relatively slow and by the month of life ranges from 1.5 to 2 cm, but the body is still transparent. The first sign of the formation of color is a dark spot-eye at the base of the tail (which gives the name of the mind – ocellicauda), begins to be visible after 5-9 weeks of life.

From three months, the color is already formed, as in adult fish, but the color is still a couple of months pale before reaching maturity.

The life expectancy of Eleotris carpet / Peacock’s goby (Tateurndina ocellicauda) is about 5 years.
