This very colorful Goby-like fish doesn't really belong to the Gobiidae family but to Eleotridae. It originates from New Guinea, the island of many stunning fish species. Males grow to about 7 cm while females stay smaller, about 5 cm.

Both sexes show bright blue coloration with many red irregular lines/spots. They have two dorsal fins (the front one is shorter). The longer dorsal fin is the same size as the anal fin. The female has a black line at the edges of both, anal and dorsal fin. Conversely, the male exhibits bright yellow edges. Both sexes have a black spot at the base of the caudal fin (hence the name, Eye-Spot Sleeper). Even though both have yellow bellies, the female shows off stronger yellow, especially in breeding condition (somewhat similar as can be noticed in Pelvicachromis pulcher species). The most notable difference is the shape of their heads. The female has a pointed head, while the male has a hump-head and a much stronger, grumpy looking, jaw. Sometimes, depending on the light angle, the male's eye will reflect red (see photo). This is not seen in females.

Peacock Gudgeon Larvae The Peacock Gudgeon is a very peaceful fish and can be kept with other peaceful species (ex. Rainbowfishes). The male Tateurndina ocellicauda will indeed show some "pushy" aggression towards the female (and other fish) when caring for the eggs. This kind of aggression doesn't lead to injuries. The male looks after the eggs on his own, but only until they hatch, after which he sees them as a snack opportunity. During this caring time he will not leave the cave, not even to eat. Therefore, one should not be surprised if one of the males vanishes for a few days. The fry will take infusoria as the first food, but after a while should be provided with freshly hatched artemia nauplii. The fry grow very slowly. The photo on the right shows Peacock Gudgeon larvae attached to the stone, the day before hatching into free swimming fry.

How do I feed T. ocellicauda?
This is a very good question, since this species is very picky when it comes to their diet. They will happily refuse all kinds of commercially prepared food like flakes, granules, tablets, crumbs, even the freeze-dried ones. But, they will readily accept live/frozen equivalents like Artemia, Tubifex, Daphnia, white/black mosquito larvae, as well as chopped Bloodworms. Properly fed Peacock Gudgeons will have a nicely rounded belly (see photo).

The aquarium water should be in the 6.4-7.5 pH range with a moderate KH. Temperature should be kept between 23-27C. Water changes of 25% should be done weekly. Aquarium should ideally be furnished with stones, roots and live plants.

I just got 2 Peacock gudgeons and they are wonderful additions to my 340 L tank. They do very well with their tank mates (7 platies, 4 neon tetras, 2 lemon tetras, 5 zebra danios, 2 bumblebee gobies, 2 orange tetras, 3 glowlight tetras and 2 algae eaters (with a bunch of shrimp). They don't prefer flake food too much, so I feed them brine shimp with my gobies and they do well. I recommend these fish!

Tateurndina_ocellicauda_3.jpg I picked up a pair of these at under 3 cm long and since they have grown to just over 5 cm, I think I was actually sold two females. Regardless, they are healthy and seem very happy. I've never gotten them to eat dry food for some reason, but they eat every kind of frozen food from bloodworm to bits of whitebait. Lovely species.

I keep 2 peacock gudgeons (male and female) with a couple of small angels, a male german ram, some sterbai corys, and a stiphodons. The male and female don't really associate too much with one another unless the male decides to do a beautiful fin display for his mate. They both spend a lot of time sitting on the gravel. They enjoy both pellets and chopped frozen bloodworms and haven't yet been too difficult to keep...although I may have to rehome them when the angels get bigger. A very beautiful addition to any aquarium.

We keep four peacocks (1 male, 3 female) in our 265 liter tank along with 3 celebes rainbows, 2 platies and an angel. These little guys are incredibly curious, to the point where they'll come and nip food from your fingers if you let them. They'll eat anything, flakes or frozen, but they seem to love frozen brine shrimp the most. Careful though, they never seem to stop spawning!
