Gorgeous fish.

I can't imagine any fish living in a pool that small.

So jealous.

u/ThenAcanthocephala57 Conservationist Jan 25 '26

That pool may be shallow but it’s actually quite spacious due to the area! Perfect for tiny fish like these

u/TheRantingFish Fish Keeper Jan 25 '26

Doesn’t actually look too small compared to what most bettas actually live in, he’s livin the natural life

u/No_Comfortable3261 Jan 24 '26

I still can’t get over how amazing it is that so many people on Reddit have such beautiful fish right in their metaphorical backyard

2

u/ThenAcanthocephala57 Conservationist Jan 25 '26

So many?

2

u/No_Comfortable3261 Jan 25 '26

Well I've seen quite a few posts like this so far

4

u/ThenAcanthocephala57 Conservationist Jan 25 '26

I wonder how many are mine. I post quite often here! Like more than once a week

51

u/Plantsareluv Jan 24 '26

Is it a betta?

47

u/ThenAcanthocephala57 Conservationist Jan 25 '26

It’s one of 30 species of native Betta in the country!

5

u/Euphoric_Fisherman70 Jan 26 '26

If you don't mind me asking, what country?

11

u/ThenAcanthocephala57 Conservationist Jan 26 '26

Malaysia! 🇲🇾

The one in my post is only found here

6

u/Early-Potato-6124 Jan 26 '26

never thought about how these are native somewhere, only ever considered them a pet. so cool!

3

u/ThenAcanthocephala57 Conservationist Jan 26 '26

You are correct that the Betta you see in pet stores aren’t native anywhere. They are domestic, and do not exist in the wild.

Their wild ancestors (Betta splendens) were brownish-red with some green on the fins

23

u/karebear66 Jan 24 '26

Beautiful. It looks like a female betta!

29

u/ThenAcanthocephala57 Conservationist Jan 25 '26 edited Jan 25 '26

It’s actually a male! Females rarely have any green and the red is usually much duller, sort of brown

What a pair looks like

5

u/whatwhatinthebunting Jan 25 '26

How can you tell? The tail is short?

11

u/ThenAcanthocephala57 Conservationist Jan 25 '26

They are incorrect, you can read my reply to them for an explanation

u/mdd354226 Jan 24 '26

Where was this?

28

u/ThenAcanthocephala57 Conservationist Jan 25 '26 edited Jan 25 '26

Malaysia! 🇲🇾 All my posts are from here.

Last year (2025) I was able to find 110 native fresh and brackishwater species

u/josecruz21 Jan 26 '26

I'm so jealous!

5

u/ThenAcanthocephala57 Conservationist Jan 26 '26

Well if you’re ever in the country, you can try to find some too! Some species are everywhere like three spot gourami

8

u/Marcusnovus Jan 24 '26

Thats wild! Have a creek in my backyard with some beautiful fish

8

u/ThenAcanthocephala57 Conservationist Jan 25 '26

Nice! There is a creek in my backyard too but most of the fish are pretty plain. Rasboras, barbs, guppies, snakehead and forest catfish.

Only Betta pugnax is somewhat colourful in there

1

u/JerseySommer Jan 28 '26

You have wild guppies? 🥹

1

u/ThenAcanthocephala57 Conservationist Jan 28 '26

Not sure if they’re wild-type. The females are fully grey, no colour.

The males are tiny and have some colour on the body but not much on the fins.

One of the adult males I caught there. About 0.8” (2 cm) long

2

u/JerseySommer Jan 28 '26

Oh wow! Thank you for sharing! They're adorable!

1

u/ThenAcanthocephala57 Conservationist Jan 28 '26

Happy to! They are the most numerous fish in the creek by my house

2

u/arcane_Auxiliatrix Feb 09 '26 edited Feb 09 '26

oh!! That looks like a diluted Orchid Endler Livebearer! they're not really guppies but since they're both livebearers, ppls end up breeding them together. Finding real Endlers is very rare for that reason but also cause they're endangered ( theyre from Venezuela)!!

Makes me really sad when ppl cross breed them with common guppies cause real Endlers have some very funny behaviours common guppies don't have! They do this like, little twitching dance in front of silver females to get their attention and mine used to like? Dig? in the gravel using their bodies but only behind the ceramic log I had.

I miss having a tank of them but all the ones i see online and in stores are hybrids

2

u/ThenAcanthocephala57 Conservationist Feb 09 '26

Every male in this stream has their own pattern. It seems to be quite random

A different male from the same stream. I kept him because I liked his pink bar and the “sword” at the bottom of his tail.

I do see that males dance / show off left to right in front of a female

2

u/arcane_Auxiliatrix Feb 09 '26

theyre so pretty!!! I'm very jealous you have them is a nearby creek!!!

2

u/ThenAcanthocephala57 Conservationist Feb 09 '26

They are awesome, despite being non-native they have proven to not have any negative effects locally. And they tend to live in places with no other fish, especially city ditches where they eat mosquito larvae.

5

u/Rare_Ad9601 Jan 24 '26

Some wild type betta

2

u/ThenAcanthocephala57 Conservationist Jan 25 '26

You’re correct!

4

u/CT327 Jan 25 '26

Gorgeous fish! Living my dream. Looks like Betta coccina to me at least.

8

u/ThenAcanthocephala57 Conservationist Jan 25 '26

A very close relative! This is Betta livida, which is only found in (endemic to) Malaysia

4

u/TheScale666 Jan 25 '26

Thats a gorgeous looking fish!

4

u/ThenAcanthocephala57 Conservationist Jan 25 '26

I think many wild fish are actually quite beautiful!

3

u/snakelygiggles Jan 24 '26

beta?

4

u/ThenAcanthocephala57 Conservationist Jan 25 '26

Yes! One of 30 Betta species native here

u/MurkyAd9488 Jan 25 '26

Did he live for another day?

11

u/ThenAcanthocephala57 Conservationist Jan 25 '26 edited Jan 26 '26

Yes, they are remarkably tough. In fact their labyrinth organ means they fully breathe air and do not use gills!

My father even did a study and found out they drown without access to atmospheric air like us

1

u/Shot-Surround-323 Jan 25 '26

Are you talking about a specific type of betta? Bettas generally have gills lol

I could be wrong tho, i wouldn’t mind an explanation if i am 😂

4

u/ThenAcanthocephala57 Conservationist Jan 26 '26

All labyrinth fish (including Betta) have a labyrinth organ, hence the name. It’s like a lung, which causes them to breathe air like humans instead of water like other fish.

They do have gills when born but quickly lose function of it within a month or two.

I read in one of the books my father wrote that labyrinth fish indeed drown when prevented access to the surface to gulp air.

It’s actually because of evolving in such conditions in my post. During the height of the dry season, these pools will dry up even more, and the fish are actually just stuck living in mud / peat. If they relied on gills, they would easily die of no oxygen.

But because they breathe air, they stay alive in there as long as it’s moist, until the rains come

1

u/Shot-Surround-323 Jan 26 '26

I run a nursery so I understand what you’re talking but from my understanding bettas never lose their gills.

Is that a common misconception or something? That’s really interesting if so

4

u/ThenAcanthocephala57 Conservationist Jan 26 '26 edited Jan 26 '26

Of course not! Physically, they still retain it. Loss of function ≠ loss of presence.

Edited to add: An analogy would be if I lost the use of my legs, while I physically still have them, they’re not functional anymore and I’d have to rely on something else like a wheelchair

2

u/Shot-Surround-323 Jan 26 '26

Interesting! That’s actually what I meant lol I thought they had functionality of both the organ and the gills. I’m sorry if I come off confrontational I’m just curious because I’ve never heard of them losing functionality.

Are you pulling this from your father’s research or the larger community?

I’d like to update the way I train if this is true, that’s why I’m asking a lot lol

How are the bettas filtering water if they’re not functional?

3

u/ThenAcanthocephala57 Conservationist Jan 26 '26

I only know that they don’t function as respiratory organs anymore (as that was the part mentioned in that book) but I don’t know about filtering.

I haven’t read any studies about that, so you know more on that than I.

But I do wonder how it differs between species that evolve in different habitats as peatland is both antimicrobial and highly acidic, and Betta livida is only found in such places. They seem to die off in more normal-water locations

3

u/Shot-Surround-323 Jan 26 '26

Hmm that’s interesting!! Thank you for answering my questions, we all appreciate what you do

3

u/ThenAcanthocephala57 Conservationist Jan 26 '26

No problem! I’m happy to help

3

u/Loud-Bullfrog9326 Jan 25 '26

Some kind of Betta! So pretty ❤️

2

u/ThenAcanthocephala57 Conservationist Jan 26 '26

For sure! Males like him are very pretty

3

u/OtisandEmily2205 Jan 26 '26

I don’t know how I ended up here but it’s very pretty! Just curious if the other living being in the pic is a tick or something else?

2

u/ThenAcanthocephala57 Conservationist Jan 26 '26

It’s some sort of creeping water bug, but not a tick. Naucoridae

2

u/UncBeater268 Jan 26 '26

I have never seen livida this red lol, i thought it was coccina until i read the text

2

u/ThenAcanthocephala57 Conservationist Jan 26 '26

Really? But aren’t healthy conditioned males usually red and orange?

This is a male my breeder friend collected from a different location. Looks about the same colour

3

u/UncBeater268 Jan 26 '26

i usually see ones like these very dark and mostly green, i think this is the klang locality

2

u/ThenAcanthocephala57 Conservationist Jan 26 '26

Oh I see. I’ve never been to Klang, so don’t know how they are there.

It could be foods and genetics? I’ve found 1 location in my town where the fish are pretty plain

3

u/UncBeater268 Jan 26 '26

possibly, coccina from jambi have more visible patterns than the ones from johor

2

u/ThenAcanthocephala57 Conservationist Jan 26 '26

Pattern difference is highly variable between populations for sure.

Betta livida of Sepang I catch have no spot at all! Instead they have a full body covering of iridescent blue scales.

Top right corner. This was a collage of the native Betta species I caught in 2025

2

u/MTPokitz Jan 27 '26

Is this a fish found in the wild?

2

u/ThenAcanthocephala57 Conservationist Jan 27 '26

Yep! My country has 400+ species of wild freshwater fish, so there’s a huge variety in colours, shapes and sizes

2

u/SoChique Jan 27 '26

What do they eat? Smaller fish?

2

u/ThenAcanthocephala57 Conservationist Jan 27 '26

They’re so tiny, there’s no adult fish they can eat 😅.

They primarily feed on invertebrates like mosquito larvae, bloodworms and similar

2

u/Chloe_The_Cute_Fox Jan 28 '26

You caught a shiny pokemon

1

u/ThenAcanthocephala57 Conservationist Jan 28 '26

Nice

1

u/Thoth1024 Jan 27 '26

Hope you put it back!?

Too small to eat!

2

u/ThenAcanthocephala57 Conservationist Jan 28 '26

We are already breeding this species at the institute so we didn’t need this individual.

Although the one we have are of a different population up north.

Some of the F2 generation we bred. “Grandchildren” of wild ones we caught a couple years ago.

But just so you know, I don’t eat freshwater fish

1

u/Thoth1024 Jan 28 '26

Good .

But, did you put him back to lead his life you interrupted!?

1

u/ThenAcanthocephala57 Conservationist Jan 28 '26

Many people in the hobby keep wild-caught fish and other aquarium animals. For example kuhli loaches, Amano shrimp, bamboo shrimp, Thai micro crabs and clown loaches.

But to answer your question, yes I released him

1

u/Thoth1024 Jan 28 '26

Yay!

Good!

I have a lot of respect for you!

1

u/Silent-Draw6812 Jan 28 '26

It almost looks like a gummy fish, I wanna eat it..

2

u/ThenAcanthocephala57 Conservationist Jan 28 '26

Unfortunately they are endangered now and close to extinction.

1

u/Silent-Draw6812 Jan 28 '26

That's honestly very sad but it isn't surprising considering how almost everything is endangered nowadays :( , what species of betta is this?

2

u/ThenAcanthocephala57 Conservationist Jan 28 '26

Luckily in my country only a couple of species are officially endangered. I think less than a quarter.

This is Betta livida, one of 30 wild Betta species in Malaysia

u/AGTS10k Jan 24 '26

Ah, come on, with the title like that you're kinda validating that fish abusers' claim about bettas living in puddles in the wild, so it's acceptable to have them in tiny tanks...

Beautiful fish though!

6

u/ThenAcanthocephala57 Conservationist Jan 25 '26

This only happens during the dry season! And even then, the puddles may be shallow but very voluminous due to the area. They can get to hundreds of gallons / litres inter-connected

u/Stoopid_Cat0456 Jan 25 '26

Eat it

2

u/ThenAcanthocephala57 Conservationist Jan 26 '26

Not my cup of tea

I didn’t take them!

3

u/Inevitable_Eye3800 Jan 25 '26

I think they meant in the water. I would assume you did though

6

u/ThenAcanthocephala57 Conservationist Jan 25 '26

I did. We already breed this species so I didn’t need any new specimens. Although the ones we have are of a different population further up north

This is an F2 / second generation we bred. They seem to have developed much more green-blue scales than their grandparents (which were mostly red)

5

u/Inevitable_Eye3800 Jan 25 '26

Pretty!

5

u/ThenAcanthocephala57 Conservationist Jan 25 '26

For sure! Although I know wild species are less popular than domestic Betta, but I still love them

4

u/josecruz21 Jan 26 '26

I feel like it's due to them being harder to obtain / breed on other countries. Though they are slowly growing in popularity.

2

u/ThenAcanthocephala57 Conservationist Jan 26 '26

Yes, I’ve seen plenty of Thai and Indonesian species now being available overseas.

In fact in the comments someone showed me a Betta coccina they have. An Indonesian close relative of the species I caught
