The Clown Killifish (Epiplatys annulatus), is one of the most colorful nano fish there is. Its stunning color makes it an amazing choice to add to a nano aquarium, even those that house shrimp. Due to its native habitat, it is recommended that tanks have low flow or possibly no flow at all depending on weekly maintenance.
These fish are great as they are micro-preadators that occupy the top portion of tanks and eat small live foods. The males will have a pointed caudal fin, hence the nickname "Rocket Killifish". Females will have a rounded caudal fin with slightly less vibrant coloration. If breeding these fish is your goal we would recommend a species only tank as other fish will eat the fry.
The Clown Killifish can reach a max length of around 1.5 inches.
We feed these killifish an exclusive diet of live brine shrimp, frozen daphnia and cyclops.

My order came in perfect. The fish were a little pale at first but colored up within half an hour. Good size. They seem very healthy, taking food right away.
These little guys & gals
Are so cute! I added 1 male and 2 females to my shrimp tank and they’re pretty active. They like to hide in the plants but the male is quite personable and seems to know me as his feeder. They’re eating frozen cyclops right now and baby brine.
I received my trio of killifish from Flip Aquatics almost 2 weeks ago, and the fish are doing fantiastic! They were packaged very well with insulation and a heat pack. They also came with a card providing useful information on how to acclimate them, as well as a nice sticker. The fish did well in my tank almost immediately and they look amazing! If you’re looking to add clown killifish to your collection, you can’t go wrong with ordering from Flip Aquatics!
They all arrived alive and healthy and are doing great in my tank. Would definitely buy from this site again.
Fish arrived healthy, and have been thriving in a species only tank specifically set up for them to breed! I have ordered multiple times now from Flip Aquatics, and will continue to do so!
I've never kept killifish before but I will likely continue to do so in the future. I had no idea it was going to arrive so small. The entire body of this little guy won't cover a dime. Having done all of the research I could handle months before I opted to take the plunge and add one to my amano nano tank ("for added bioload" lol). I had concerns when adding him in that he would simply disappear into the growth and never been seen again. Quite the opposite. He made himself right at home, coloring up within an hour; exactly as brilliant as shown in the pictures. He cruises the tank, he's eating quite well including northfin veggie pellets presoaked, muddled and poured in. Approaches the glass when someone comes to visit.
A fantastic addition.
Best quality fish! I will only order through this company online!
Arrived promptly and healthy with great color despite the stress of travel.

I waited months for Flip to get females in, because I trusted the stock quality. They are nearly adults, with healthy shine and that signature glowing eye. My male instantly started courting them. These are one of the hardiest breeds I’ve kept in a nano tank. Really love them.

These all arrived super healthy and ready to go! I love these feisty little fish, and definitely recommend Flip Aquatics 😊
My fish arrived in fabulous condition, beautifully packaged, they ate right away and settled in to patrolling the top of the tank. I love these fish and I've got plenty of females for this male to occupy all their time lol.Thank you Flip Aquatics for another amazing delivery
I received 10 very healthy killis. They pretty much stick to the surface and get very excited at feeding time. They are social and seem to carve out "personal space" but still interact. In any case, everything was well-packed and arrived in good shape. Took a day to color up.
These three little females arrived seemingly healthy and alert, colored up well once in my established tank that was solely dedicated to them. However, despite my best efforts (tank parameters well within the ones the fish had come from, feeding them baby brine shrimp and daphnia, nearly no flow sponge filter) I lost two of the females within the first two weeks. The third female is still alive, and is now sharing a tank with one of my male rocket killifish, and seems to be doing okay.
I was sent two males and one female 😔 otherwise they arrived healthy.
Great looking fish, perfect fit for my fluval flex 9. Ive ordered them twice now and they arrived in a timely manner and in good condition
Healthy vigorous little guys. I'm already seeing breeding activity!
Arrived healthy and in perfect shape!
I ordered the trio of 1M2F, expecting them to be tiny, since most clown/rocket killies aka banded panchax aka annulatus, depending on who you ask, are shipped SUPER small. They're a little bit hard to find, and I've been told that's why. These fish showed up at 1" or so already! I added them to their own heavily-planted tank and they have been doing their killifish thing, which is to say they mostly hang around, and occasionally zoom after each other or after prey/perceived prey. They definitely enjoy live foods but are also happy to take very small food like powdered flake or micron-size foods. They have been showing some spawning behavior so I'm hoping for fry someday soon!
Love, love, love these little guys. Arrived perfectly healthy, active, and are doing great in their new home!
Overall good but the females were very small and one died the very next day. It didn't seem too healthy but the other one is fine. A lot smaller than when my male came in.
Very pleased with my fish. Very nice size. Never had any that big. Love them.
Todos llegaron sanos y activos definitivamente un gran lugar para ordenar sus peces
I ordered 3 female clown killies, because I have a pair and the male stresses out the female. The 3 were nice and healthy, and were all female! So now my male has 4 females to divide his harassment between 😂
