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.

Arrived safe and healthy

I was so happy to find this company! They have such high standards and their fish variety is awesome. Finding clown killis was difficult but I was happy to find them at Flip. All my fishies arrived safe and healthy! They colored up the very next day. I went with the fastest shipping option and it was a great experience! One week later and my killis are breeding already!

Worked Out Well

I ordered nine Clown Killifish. They were in two bags, separated by gender. All nine arrived alive and appeared well. They've now been in my tank two days, and they seem to be doing fine. The overnight shipping isn't cheap, but if you can't find a certain fish locally, this is a viable alternative.

Healthy fish happy customer

I ordered these for my son's tank, I was very hesitant because the last company I ordered fish from we had a terrible experience. But out lfs only had a couple of these clown kills in stock and we needed to get more. The customer service is top knotch at flips and the fish and shrimp we ordered are thriving almost two weeks later. These clown kills were eating and not acting stressed from day 1. Very pleased.
These fish are so interactive and fun, no issues with shrimp tank mates. As soon as you come up to the tank they are front and center. Not to mention they're beautiful.

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!
