Does this fish kill with its appearance? Is that why it is called the Killifish? We are about to find out in this brief post….

This rare gem of a find has what looks like — best way for me to describe it??? — red polka dots running all across the length of its body. Its body is yellowish - whitish, and its pupils are dark like coal. Not a bad look, I would add.


What can it eat? Well, try not to think too hard on this and just go with something ‘carnivore’ (as that’s what this fish truly is, at heart). Depending on its size, you can give it one or more of the following : daphnia, brine shrimp, larvae from mosquitos, mysis shrimp, or blood worms.

It loves flakes, frozens, and even some Betta treats, if you can manage to snag a few and leave them in your reserves. When it’s feeding time, drop in the food, little by little (not all at once) and see how the fish responds in its speed of consumption, to determine how hungry it was….


It originated first in Canada, Africa, Europe, Argentina, and other spots of the globe. It has been seen all over, and some debate continues to arise as to which of these places it was solely at, originally, or its ‘sole place of origin’.

You will not find this fish, for unexplained reasons, in Antarctica ; neither will you come across one in Australia. By the way, I did say Europe was a place it came from, originally, but just the southern half (Northern Europe excluded). Now let’s talk about who you can bunk this fish with….

Roommate Situation

A blessing of a good roommate is something you should always strive for, if you truly — deep down and sincerely — want to keep your fish happy throughout its entire life, and I can not stress that matter enough. It’s as important as getting a good human roommate, if you’re a human being. Fish need to be happy, too. Now, the male Killifish is sometimes known to be a bit feisty, though that does not mean that it’s a killer (like it’s name would make it sound). Yet, for the most part, this fish keeps peace and order.

Tetras work best. This has been shown, time and again. And you’ve got many Tetra types to choose from : Cardinals, Rummy Nose, Neons, and plenty more!

Other Facts to Note

The Killifish species count is at nearly 1,300 ; think about that deeply, for just a sec, and you will notice how insane that is. To be exact, there now are 1270+ different discovered Killifish species out there. And I’m sure there’s even more to discover, yet! New things are found every single day….

To further add to your rush of adrenaline (that came from hearing this last fact), let me add some more —- the biggest Killifish recorded was 9 cm. That is insane! So buy your Killifish today…
