Name: Tateurndina ocellicauda| Origin: Papua New Guinea| 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
