Clown Killifish

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.

Please Note: All fish shipments have a 100% Live Arrival Guarantee when shipping with FedEx Overnight (1 Day) option. All other options void our Live Arrival Guarantee for fish. 

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.

Very cool fish

Definitely a top water fish, almost always hanging out there. In great health and size. Three weeks in quarantine, perfect shape the whole time, and he’s getting added to his home today. Gotta say, Flip Aq makes the quarantine process feel unnecessary. But I’ve been burned by other sellers so it’s ingrained in me by now.

Great Service! Quality fish!

I am very pleased with my recent purchases! Rob’s response to my last minute request was greatly appreciated. The fish arrived in perfect condition, were packaged with great care and with detailed instructions on how to introduce them to their new home. I’ll definitely be a returning customer! Thanks to the Flip Aquatics Team!

Was looking to bring a bit more life to my shrimp tanks, but was difficult to find fish suitable to go with them. After quite a bit of research, I decided clown killifish would be my best bet, unsurprisingly I couldn't find them at my local pet stores, which was ok because I knew Flip had them. I was a little worried about shipping fish across the country, but after all my other orders from them, I was confident they'd be alright. Tiny when they arrived, but my first group seemed to triple in size in a few weeks, and I expect the newest group to do the same. So far no negative impact on the shrimp. Took to fry food quickly, they also like freeze dried daphnia and go crazy for frozen brine shrimp. Love the color and movement they bring to the tank. Hard to go wrong with Flip Aquatics!

Clown Killifish

Fish arrived alive, while their colors were a little pale, they quickly regained it once they were settled into their new tank. Thank you!

Shipped fast, packed well

I had some reservations about having livestock shipped to Colorado during our winter but FlipAquatics was the only online seller of sexed female clown killifish and I really wanted to give it a shot for my male clown killifish's sake! Shipping was quick and the package was well insulated. The heat pack was still warm to the touch when I opened the box which was a nice surprise. The 3 females I ordered looked great when they came in and they acclimated quickly to their new tank. I've had them for just about a month now and they're really starting to fill out and hopefully I'll see some baby killifish soon. Thanks FlipAquatics!
