Care: The Golden Wonder Killifish should be kept in a school of 3+ in a 20 gallon or larger. I have personally found that filling the tank halfway and having a lot of branches, leaves, and other vegetation above the top of the water gives them the ability to hunt for bugs above the water (which is what they normally do). The Killifish should have clean water with little flow and at temperatures around 72-77 degrees Fahrenheit (22-25 degrees Celsius) with a pH of 6-7.5.
Diet: The Golden Wonder Killifish should be fed high quality pellets, meaty items (such as brine shrimp, blood worms, mysis, and daphnia), and live foods such as small crickets, small shrimp, and small guppies (Optional).
Tankmates: The Golden Wonder Killifish can be kept with various tankmates, as long as the tankmates are not aggressive towards the Killifish and are not able to fit into the Killifish's mouth. Some good tankmates include Apistogrammas, larger tetras (2+ inches), corydoras catfish, and Barbs
Breeding: The Golden Wonder Killifish can be bred by separating a male and a female into a tank by themselves. The Male will flare his fins and perform a dance to try to entice the female to breed. If the female decides to breed then the female will lay her eggs on some vegetation which will hatch in 14 days. The eggs are pictured below
To sex the Golden Wonder Killifish, look at the coloration. The Males will be a lot brighter than the females and larger. Below you can see a male on the right a female on the left

Anatomy: The Golden Wonder Killifish has a very interesting anatomy which I have decided to illustrate here. First, the killifish has no dorsal fin and very small adipose fin which allows it to float at the top of the water to wait for prey to fall into the water. Because the Golden Wonder Killifish is at the surface of the water, it is vulnerable to terrestrial predators (mainly birds), so it has developed a third eye on the top of it's head called the parietal eye as pictured below ontop of it's head to see any potential predators.
The Golden Wonder Killifish has also developed a trapdoor like mouth, which can open surprisingly wide.

Behavior: The Golden Wonder Killifish is considered peaceful, but it is a micropredator and will eat whatever fits in it's mouth (so no neon tetras, shrimp, and other small fish and invertebrates). Here is the video that got me interested in them which will show it's behaviors and go to show how big their mouth really is
