Die Pastellgrundel oder Schwanzfleck-Schläfergrundel (Tateurndina ocellicauda) aus Papua-Neuguinea ist eine kleinere freischwimmende Süßwasser-Grundel aus der Familie der Schläfergrundeln (Eleotridae). Aufgrund ihrer Farbigkeit ist sie ein beliebter Aquarienfisch.
Die Pastellgrundeln werden bis zu sieben Zentimeter lang. Ausgewachsene, alte Männchen haben einen ausgeprägten, bulligen Kopf, Weibchen weisen einen rundlichen Körper auf. Die Afterflosse der Weibchen ist schwarz gerandet, dieses Unterscheidungsmerkmal tritt jedoch bei einigen Aquarienpopulationen nicht auf.
Die nächsten Verwandten der Pastellgrundel aus der monotypischen Gattung Tateurndina sind einige Arten aus der Gattung Mogurnda.
Die Grundeln leben im östlichen Papua-Neuguinea, nördlich des Owen-Stanley-Gebirges in kleinen Regenwaldbächen mit kiesigem Grund und Unterwasservegetation.
Von der natürlichen Lebensweise ist wenig bekannt. Es wird berichtet, dass die Pastellgrundeln sich in Gruppen im freien Wasser, aber in der Nähe des Bodengrundes aufhalten. Bei Störung fliehen sie in die Vegetation am Rande des Gewässers.
Im Aquarium stellen sie keine besonderen Ansprüche an die Temperatur, die Härte, oder den pH-Wert. Sie bevorzugen carnivores Futter von Wirbellosen. Die Fortpflanzung erfolgt, nachdem ein Paar einen geeigneten Versteckplatz gefunden hat. Das Weibchen legt 40 bis 200 Eier dicht nebeneinander auf eine harte Oberfläche. Das Männchen bewacht das Gelege in unmittelbarer Nähe, wobei es mit den Brustflossen frisches Wasser zufächert, und kommt kaum zum Fressen. Die voll entwickelten Larven schlüpfen nach etwa 10 Tagen. Pastellgrundeln sind zurückhaltend und friedlich, manchmal kommt es jedoch vor, dass sie anderen, kleinen Fischen Flossen anknabbern.

The peacock gudgeon or peacock goby (Tateurndina ocellicauda) is a tropical freshwater species of fish in the family Eleotridae that is endemic to the eastern part of Papua New Guinea.[3] It can be found in schools hovering over the substrate in rivers and ponds. This species can reach a length of 7.5 cm (3.0 in). It is currently the only known member of its genus.[4]
Due to the lack of fused pelvic fins that are seen in true gobies, T. ocellicauda is not actually a goby and is instead placed in the family Eleotridae. Fish in this family are known as "Gudgeons".
The Body coloration of T. ocellicauda is blueish and silvery with pink, yellow and black marks along the body and fins. On the sides of the body there are red lateral dotted stripes and a yellow abdomen. On either side of the body, there is a single, large black spot near the start of the caudal fin.
Sexual dimorphism is present in Taterundina ocellicauda. The males will be slightly more colorful, develop a large nuchal hump on their foreheads, and will be somewhat larger than the females (7.5 cm as opposed to 5 cm).The females will have a more brightly colored yellow belly and will have a black bar running along the edges of their anal fins. The females also have a more streamlined body shape as opposed to the more round body shape seen in males.
T. ocellicauda exhibit suction feeding as they prey upon insects, insect larvae, and small crustaceans. In captivity they will accept Brine Shrimp and Bloodworms.
The males of T. ocellicauda will choose a spawning site, usually a cave or crevice of sorts. The males will then swim in a circular pattern near the entrance to the spawning site and will flare their pectoral fins at passing females. If unsuccessful, the male will attempt to nudge the female into the spawning site. If the female agrees to spawn, she will lay 50-100 eggs within the spawning site where she will stick the eggs to the ceiling and walls of the site with use of adhesive found on the eggs. The male will alternate between fertilizing eggs and ensuring there are no potential intruders near the entrance to the spawning site. Once all the eggs have been laid, the male will chase away the female and assume all parenting responsibilities. The male will fan the eggs with his fins for 8-10 days to ensure that they are well oxygenated and that no fungi will grow on the eggs. After 8-10 days the eggs will begin to hatch and the male will leave. After around 2 days the larvae will begin to swim on their own before reaching sexual maturity at 6-8 months.
T. ocellicauda are a peaceful addition to community tanks of 15 gallons or more. The males may be territorial to other males. Lighting should be low and there should be many places for the Gudgeons to hide and take cover. Ironically, the more cover that is available, the higher the amount of activity by the Gudgeons. PVC pipes can offer excellent spawning sites provided there are numerous plants such as Java found nearby.

Tateurndina ocellicauda est une espèce de poissons tropicaux vivant en eau douce, de la famille des Eleotridae. C'est la seule espèce de son genre Tateurndina (monotypique).
Tateurndina ocellicauda est endémique de l'est de la Papouasie-Nouvelle-Guinée[1]. Cette espèce se rencontre dans les rivières et étangs et couramment dans les ruisseaux de la forêt tropicale[1].
La taille maximale connue pour Tateurndina ocellicauda est de 75 mm[1].
Le genre Tateurndina a été choisi en l'honneur des frères Tate, George Henry Hamilton Tate (1884-1953), botaniste et mammalogiste américain, et Geoffrey M. Tate (1898-1964), collectionneur, tous deux collègues de l'auteur, John Treadwell Nichols, au Musée américain d'histoire naturelle pour leur participation à la Archbold Expeditions to New Guinea durant laquelle l'holotype a été collecté[2]. Le suffixe urndina fait probablement référence à la proximité de ce genre avec le genre Mogurnda[2].
Son nom spécifique, du latin ocellus, « petit œil », et cauda, « queue », fait référence à la tache présente à la base de sa nageoire caudale[2].

Tateurndina ocellicauda is een straalvinnige vissensoort uit de familie van de slaapgrondels (Eleotridae).[1] De wetenschappelijke naam van de soort is voor het eerst geldig gepubliceerd in 1955 door Nichols.

Cá bống công (Danh pháp khoa học: Tateurndina ocellicauda) là một loài cá nước ngọt nhiệt đới và là loài đặc hữu của khu vực phía đông của Papua New Guinea.
Nó có thể được tìm thấy trong các luồng nước và lơ lửng trên các chất nền trong các con sông và ao hồ. Loài này có thể đạt chiều dài 7,5 cm (3,0 in) TL. Nó hiện đang là thành viên duy nhất được biết đến trong chi của nó. Mặc dù cá bống công là loài hòa bình, và chăm sóc khá dễ nhưng nếu không có đủ chỗ trong bể thì con đực và con cái trở nên hung hãn. Có ít nhất 10 gallon (40 lít) được đề nghị cho một nhóm từ tối đa 4-5 cá thể. Với cá bống công, con đực có một cái trán rõ rệt hay một vết sưng. Con cái có một sọc đen ở rìa của vây lưng và vây hậu môn.
