Chili Rasboras (Boraras brigittae), also called Mosquito Rasboras, are cute, tiny nano fish from Southeast Asia. They grow to about 1 inch and stay peaceful with shrimp and other fish. These guys are known for their vibrant color and active schooling, making them a lively addition to any tank. This species is suitable for community freshwater aquariums. They like soft water and stable water parameters with a temperature between 72-78 °F. Give them plenty of live plants, hiding spots, and driftwood to encourage their natural behavior. Providing these conditions makes their colors even more intense and helps them feel secure. Feed them high quality flakes, soft pellets, or frozen and live worms.
We sell mostly captive-bred chili rasboras, rarely wild fish, so you get healthy hardy stock. These have been very popular, with many already sold to happy aquarists. We have extensive experience keeping Chili Rasboras healthy and stress-free through our 14+ day quarantine process, ensuring they arrive in top condition. We keep young fish in our inventory and ship via overnight with UPS, note shipping delays can happen, but we do our best to ship fast. Each item is carefully packed for safe arrival, and please review our shipping and return policy before purchasing. Start with groups of 10 or more to natural schooling behavior in your tanks.
Our Chillis get a varied diet to stay healthy and show bright colors. We start with NorthFin flake foods, crushed small so the tiny fish can eat easily. We also offer pellets, live foods, and frozen treats to give them all the nutrients they need.
NorthFin Flake Foods: Finely crushed for tiny mouths
Pellets: NorthFin Nano Bits and Community 0.5 mm size
Live Daphnia: Our favorite food for energy and fiber
Frozen Foods: Baby brine shrimp, cyclops, and frozen daphnia
Micro Worm Cultures: Small protein-rich treats for growth
Chili Rasboras are peaceful fish from the wild streams of Southeast Asia. In their natural habitat, soft water flows through forests rich with live plants and hiding spots. Mosquito Rasboras live in groups and often share space with shrimp. To help them thrive, stock them in well-planted tanks with gentle flow and provide plenty of places to hide.

At Flip Aquatics, we prioritize the well-being of our fish. We only ship fish through overnight UPS shipping to cut travel time and reduce stress. Your fish go in breather bags that have no air pocket, these special bags let water breathe without the addition of oxygen, to reduce water movement thus reducing stress on the fish. Each order is packed in an insulated box made from recycled plastic to keep temperatures steady. With our 100% Live Arrival Guarantee, we’ll refund or credit any losses, and if there’s a complete loss, we’ll reship your order at no extra cost.
Honestly, I couldn’t be happier with my experience with Flip Aquatics.
From the very beginning, Em and Leathyr were incredibly attentive, kind, and truly cared about making sure everything went right — especially with something as delicate as shipping live fish to Puerto Rico.
I was honestly a bit nervous, but they stayed in contact with me the whole time, answered every question, and made me feel completely confident throughout the process.
When my Boraras brigittae (Chili Rasboras) arrived, I was genuinely amazed — they came in healthy, active, and beautiful. I ordered 16 and they even sent 2 extra, which meant a lot to me.
You can tell they really care about their animals and their customers, and that’s something that’s hard to find.
I’m truly grateful for the experience, and I would recommend Flip Aquatics to anyone without hesitation.
1000% recommended 💯
THANKSSSS 🤗
Bought chili's got all merah rasbora so yeah really disappointed.
My order of chili rasboras arrived safely to Texas. I am happy with my order.
This was 2/2 of my first order placing with flip aquatics and boy am I impressed. All of the fish arrived healthy and only 2 died. That is 5 stars for sure. We can never control everything but I can say they do. A good job of packaging and making sure whatever you order arrive alive. They are all thriving and enjoying the other chili and phoenix rasboras in their new home. They’ve colored up nicely too!
After 6 months with these fish, I can confidently say they are from a healthy background. They first arrived pretty pale, but over the months their colors have developed tremendously!
When they came, they were fairly cold despite the heating pack, but this was also during a very busy shipping period so they probably spent more time than usual in the cold.
Pictured are some of the fish, which are incredibly difficult to photograph!
I ordered 7 chili rasboras and received 8, 2 died within a week but the others are thriving and colored up nicely! Will be ordering more when back in stock! I also ordered 4 pygmy corydoras and 1 died the first few days but others are well and happy! Thank you Flip Aquatics!
Received all healthy and after two weeks are still thriving and really coloring up! I will definitely be ordering from Flip Aquatics again!
I may have left a review previously when I first received them but wanted to share that they are all still doing well, to attest to their health!
I ordered five chili rasboras and received six healthy little fish! All of them survived shipping, and they are doing well! They acclimated quickly to my tank, had no issues feeding them crushed flakes and micro pellets right away, and they joined my existing school with no issues! I love these little orange fish, they brighten up my tank! I definitely would order again!
Swim actively around and through my scape. I've read they can take a while to color up but they look healthy and are eating great already. Wish there were more than 15 when I ordered but they sell out quick. They have no interest in my shrimp. Working perfect to add movement to the mid to upper layer of my tank.
I was disappointed when I figured out that I didn't receive Chilis but another (maybe 2 other) type.
I had already fallen in love with them before I started second guessing the morph - they werent getting as red of the single chili that was already in the tank.
A larger nano tank looks so full of life with nanos. Flip did address the situation with me not receiving Chilis in the form of a partial refund which was very nice of them.
I've had places in the past just not respond to me at all.
The rasboras I did get are doing very well, however. After acclimating, they were nomming down baby brine shrimp and fry super micron shrimp patties maybe a couple hours later.
So I did a pickup on my last order, looking to save some $ on shipping and I'm close enough to do so. On my way back a robotic police camera snapped a picture of my license plate and I got a $135 ticket! I never have a problem getting busted if I'm breaking the law, but not by a robot! Guess I'm old school, but I think a real police officer should have to pull you over, fair & square lol
Anyway, the aquatic life that Flip Aquatics puts out is always top notch, as is the staff that makes it all possible. It's all about the animals but without a happy, knowledgeable staff servicing the customer it would fall flat. Starts from the top so a big shout out to Rob and everyone else making it all happen.
Good job as usual, & yes, worth the ticket!
It was my first time ever having fish sent to me in the mail and was happy with the experience. I got them the next day. I like the breather bag thing that’s pretty cool. My only problem was when I got my box the heat pack was freezing my bag of fish were suuuppeer cold. My fault for not checking that the weather was gonna be frost this week. Other then that the fish colored up after I got them all situated and acclimated to the room and then the tank. Your fish look so good in just one day of being in tank. I’m very happy with my purchase.
It’s hard finding Chili Rasbora out there so I was excited to find Flip Aquatics had them in stock. I placed an order for 12. Sadly, all of the Chilis I ordered were DOA. Amanda helped me out and had a new order shipped out overnight and they all appear to be doing great in their new home, not a single DOA.
Ordered 4 chili rasboras to add to my school of 6. They arrived healthy and and are doing great!
Fish arrived on time and in perfect health! Only regret is I was only able to purchase 5!
Chili Rasbora | Boraras Brigittae
The Chili Raspboras I ordered arrived well packed and on time. And 7 are still alive and thriving in my little shrimp tank.
All six arrived happy and healthy. They acclimated immediately. They are super personable and coloring up nicely...especially around feeding time! 🐟🩵
All are happy
Ordered 8 Chili Rasboras for a 10 gallon nano tank, received 9. All arrived healthy, active and are enjoying the company of trumpet snails and cherry shrimp.
I ordered 22 chilis, all arrived very well, alive, and alert. They have all survived the few weeks I have had them. Great fish, more active than I had imagined. They are kind of mellowing out now and getting comfortable and are very fun to watch. They actually enjoy the company of cherry red shrimp and Pygmy corydoras, they hang out together. Never expected that, very cute. Thank you.
Came in healthy, one was a bit skinnier and I thought I’d lose it overnight but they all looked great by the morning.
As always they came well packed. Starting to brighten up and they dig BBS.
Love it
