My Black Neon Tetras have survived several disasters including a three-day power outage where our house temps plummeted to 42 degrees Fahrenheit. They outlived most the guppies. Highly recommend them.

[@kevinchandran1902]

Useful info as always, thanks Nick! It'd be really cool to see a cardinal breeding project in the future.

[@maryglover8283]

Thank you for showing us these😃

[@rogerhuggettjr.7675]

My fish store owner told me that cardinals and rummy nose tetras are two of the worst fish for adapting to new environments. I had a hard time getting 6 cardinals established is a tank with other peaceful fish (corys, cherry barbs, aquatic frogs, white clouds). After I finally had a couple weeks without one dying I had an ick outbreak that only killed the cardinals and cherry barbs. I'm sticking with neons now that have had no problems in my other tank.

[@ThermicLight]

It's interesting how people have such differing experiences. Mine being similar to your exp in losing cardinals. Now I have happy and healthy neons and so glad to have them. Personally I think the biggest difference is based on the health and quality of the fish than the type.

[@blessedbeauty2293]

​@ThermicLight - I agree with you. That's why he also mentioned if you get them from breeders who care, you shouldn't have any problems.

[@yashtapase3821]

4:06 I love the way twiiink cories and hill stream loaches do ❤😂

[@craigquinn8225]

I've had loads of fish over the years, one of the most hardie, that never gets a mention. loaches, more specifically, kuhli loaches. I've never lost or killed a kuhli loach. sometimes they go missing, but you find it again. I've been keeping fish for nearly 30 years now. and pretty much always had them.

[@antonioviray5619]

True. One of my favorite.

[@ehsanhaidary9766]

Just my experience - I've had heaps of barbs over the years. Tigers and Rosy barbs are nippy, but the cherry barbs aren't. Cherry's are very peaceful

I'm so glad Nick mentioned Mekada Japanese rice fish, I just bought some eggs from an eBay seller. I hope they all hatch & grow.

[@WackWacky-vc5ed]

@ffxfgxsfxxxg2419 I think because he could not find any in his local pet shops and if he got them from eBay it is probably from a seller in america🤷

[@mr.octopus6972]

The things I've done to those guppys 🤦 I even use them to cycle tanks. Never succeded in killing one.

[@michaelshaw8370]

Way back in the Stone Age yes the seventies 😂 when I started fishkeeping. A local friend had an established pond in the garden of a house he bought. The previous owners had netted out their goldfish before moving out. Along with most of the lily’s. But there was still a wide range of other established plants. In late spring he put in a batch of WCMMs. They thrived even during winter with over a foot of ice. So darn strong and hardy. He would as they multiplied harvest once a month. Splitting them into two groups some in totes/ tubs in outbuildings unheated they even spawned as long as the totes did not freeze during the winter. The others he would over a week increase the water temp to acclimate the fish to community tropical tank temps. The same methods worked for me for both standard and long fin variants

[@RobDouglas3]

Great video. Thanks!

[@albino658]

While the Giant Danio is a hard to kill fish, it gets along with basically no other species. Do not put them in a community tank with other, slower, mid-level species. They’re large and aggressive and they know how to use both those traits.

[@yashtapase3821]

Anyone wondering you can also add bristlenose plecos to this list 😅

[@ryaquaza3offical]

I feel like Bristlenose plecos need a shoutout. my beloved 10 year old Sherbet I rescued from my friends tank after the entire tank completely got nuked from orbit. The entire tank just turned green and smelt awful killing all his barbs in the process, he thought everything immediately died soo he took 3 days before he cleaned it to mourn. The water just festering the entire time Guess who was found COMPLETELY FINE in the castle, that’s right, Sherbet. I then asked to take him off my friend since he wanted to get rid of the tank all together and lo and behold, the lil dude was perfectly healthy somehow. That day I learned bristlenoses are basically immortal soo they do deserve a mention imo. My little guy I’ve had for 4 years now after the incident and no issues here ether

[@ollieworth7341]

my grandmother thought she killed mine, threw it outside, and it was still alive when i managed to find her. not a bristlenose, but a 2.5ft regular pleco. theyre resilient and excellent at being invasive because of it, but im glad that she's still living out her life in my neighbours pond, bless my vet for helping me but yeah. knife wound from a lifelong fisherman couldnt even take that pleco out, nor could the eagle that tried to grab her two different times. survivors. they thrive anywhere

[@qcaquaholic]

I haven't been able to keep hillstream loaches alive for more than a few months. I put them in a 75 gallon with some decent flow. For me, it's corydoras, then kuhli loaches, and then rhadinocentrus ornatus shockingly enough.

[@willembastiaan743]

Hillstream Loaches need more than a decent flow. I advice at least a group of 5, a lot of oxygen and not so many stress. They are no beginner fish as Nick suggests.

[@nerimadaikon5516]

Just bought 5 albino corys on Amazon because of this video. Fingers crossed.

[@tonycamplin8607]

Don't know if things are different in Australia but I don't agree with you. Cardinals definitely aren't an easy fish, nore are hillstream loaches and endlers I've never had any luck with either. Not a professional like you but I've been keeping fish for over 60 years.

[@jessicawalden]

I rescued a lil albino Cory from a tank where the other fish picked at it or it had fin rot it litterly had no fins she just scooted along the bottom and with clean water and food she grew lil funny fins back and I've had her for over a year now

[@BulusKursunlu]

Cardinal Tetras are some of the most easily killable fish in the Netherlands. Are they stronger in Australia?

[@tonycamplin8607]

Bulus I completely agree with you. I'm from the UK.

[@benc3214]

@@BulusKursunlu I’m in Australia myself and my Cardinals keep disappearing, not all at once slowly over 6-9 month period. No other fish die or have any disease at any time. So unless Nick has a special kind of Cardinal that I’m not getting here in Aus I can’t agree with that choice.

[@BulusKursunlu]

@@benc3214 honestly I think Nick's a great breeder and picks strong fish for his shop. But, the average fish shop might be less knowledgeable or just buy bad quality fish.

[@Aquafinity]

My favorite beginner fish are harlequins rasboras and black neon tetras. Super hardy fish.

[@jasongoodrich1374]

I have an angel that has survived a bacterial infection that took out 2 of my other angels, callamanus, and then fin rot (a series of unfortunate events) and she's still going strong. I don't name many fish but she's earned the name Beyoncé because she's a survivor.

[@Liukanginthehouse]

I started this hobby last month and it's already been a rollercoaster... i literally have half of the species mentioned in the list and they are awesome. i would recommend kuhli loaches, a honey gourami or a bolivian ram (single)

[@HunterWHansen1]

Awesome video man! I’m fairly new to the hobby and looking to stock my 20 gal cube. Perfect timing. Any thoughts on Venezuelan Coreys?

Yeah, I know he just said giant Dan's are super peaceful, but those fish are little psychos. They nip and bite. They're fast they jump out.

[@Peregrine1989]

I agree that Sewellia Lineolata and the entire Genus of Sewellia is really hardy, which is why they have managed to thrive even with how few numbers were in Australia when import restrictions started. But I feel its important to add that Hillstream Loach is a much MUCH wider catagory then you have used it here (including Borneo suckers and Lizard Loaches) and you probably should have been more specific as many of those are quite fragile.

[@benc3214]

I have terrible luck with Cardinals i seem to have to replenish the stock on a yearly basis. I very rarely see them die they just vanish. It may be the stock im getting but the last lot i got from my LFS were terrible i shouldn't have bought them.

[@erz5386]

These last 2 seem bullet proof but I'd like something else to pop in with them in a 20L tank. Would any on this list make a good tankmate with perhaps just 1 or 2.
