Do you keep rainbow sharks?

[@Ibeencocojamar]

I didn't get notified for this video, but I guess its a bug. I love rainbow sharks and their look, don't plan on keeping anytime soon, but is on my wishlist for the FUTURE! Love the video!

[@HNUmaker]

I just got one today! 😀

[@spongescenes8115]

Heck yeah I love them

[@adamn1915]

I got one and it was eating my black skirt tetra’s tail

[@c_fletch9325]

Bay Area Aquatics I’m picking up mine in a few weeks (: he’s going into my 65gal community tank

[@julienmercier2114]

I had an albino one that lived for eight years in my 35 gallons, eating mostly sinking wafers. It was unusually gentle for a shark, never chasing other tank mates, which were mostly tetras, swordtails and mollies. Baby swordtails felt safe being close to it, while he was the biggest fish in the tank.

[@JeremyGoneWildPets]

I LOVE rainbow sharks. And red tail sharks foo. I’ve never had a tank big enough for one. Some day.

I had an albino rainbow shark for many years called Rambo. He swam around the tank so gracefully, and he was pretty aggressive too. Rambo is still my all-time favorite fish ❤

[@SnazzySki98]

I used to have a 125 with a red tail shark, albino rainbow, regular rainbow and a platinum rainbow with a ton of mbuna. Worked great I wish I had video this was like a decade ago. There was so much aggression in that tank but everyone was healthy and happy for the most part.

[@quentinrowe6432]

I've got three of these in a 20gallon tall tank and have had them In there for about a year. Two of them are 5+inches the third is about 4. They rarely chase each and over all seem happy

I have 12 in my pond with 1 bala shark. They get along pretty good

[@vulcano9200]

I had one for 12 years, and it would live even longer if my aquarium water heater wouldn't fail. Crazy resistant fish i love it. His company was a Raphael cat fish that was even older.

[@dmvlex-kh9es]

I just got a rainbow shark. It’s a really awesome fish!

[@foxxul]

My Albino Rainbow is pretty relaxed. At times, he only “chases,” more so shoos away, my Pineapple Sword and Female molly. Those are literally the only two fish he shows aggression towards. It’s usually when they go near his cave. Love watching him try to eat from the surface, as he refuses wafers and everything else.

[@chrishifter]

Rip your molly

[@ryanhoke153]

Just got my first rainbow shark. Called him Dio after the singer. Not very big. Couple plecos. Plenty of Cory cats and a few guppy’s. And one Otto. He does chase my guppy’s a little bit no major issues so far. I do plan on getting a bigger tank soon. Currently in a 30. So far so good. But am expanding soon.

I have a rainbow shark, albino rainbow shark, red tail shark and also 2 balas sharks...all started out as tiny babies in a 60 gal...once they got to be a year old I had to move them out of the tank..and seperate them all except the balas ..they get along great

Balas are schooling fish. They like balas :)

[@laceytopmiller794]

@@DilettanteCulture yes but balas get huge...and are now in a much bigger tank..I tried to move the red tail to the bigger tank but he wasn't having it...he likes the 60 gal and his boat

[@Jstroman221]

It's a great fish I have had mine for over 7.5 years and shows no signs of slowing down. It has however gotten more aggressive over the years, I remember when my rainbow would share food with my corries but that didn't last. It's still a great fish I just keep it with tetras and he has reign over the entire bottom of the tank. Eats everything even flakes from the surface and the best part is watching them graze around all of the tank surfaces and algae from live plants. Just keep an eye out for the aggression as they mature around the 4-5 year mark.

[@aleyaartim3096]

My current one is 10 yrs old n going strong. He loves scraping algae and hide in his cave if we're around but comes out to graze when we're not there :) In 42g with a paradise fish.

[@baileymyers688]

What size tank?

Yes

I have an albino rainbow shark with 3 Bala sharks they get on fine but my Balas were established first and 7 inches so that may be a factor.

[@SpiritualPeach]

Your tank is beautiful. Where did you get your driftwood? Did you purchase it or find it and treat it? Looks amazing and very well set up.

Thank you! I got it from Houston Manzanita! Let Adam know Bay Area Aquatics sent you, he's got great customer service and pricing! (He's not a sponsor, just a vendor I use and really like)

[@tigersnakegaming5530]

I have far less common ghost shark at around 6 inches and he is pretty chill with everyone except my 3 inch rainbow. He will chase him into a corner. I’ll have to monitor then once the rainbow catches him in size.

[@kaivoisin7715]

dont need advice on keeping them. Just clicked cause Im glad someone else appreciates them

I have a 75 gallon with red tail shark and 4 rainbow sharks with a bala shark in together and they play a little bit but they don’t kill each other lol. Got them all as babies so I think they just grew up well with each other

[@xX_Gr3g_Xx]

Thanks for this Guide. I used to have a cool rainbow shark a few years ago. He grew to be 4-5 inches and had him for a couple of years but sadly though my family had to move and we gave him to a school teacher who kept him in his tank with guppies. The kids loved seeing my rainbow shark. He died shortly after my family moved though and I haven't owned a fish since then but maybe soon I'll be getting another one and watching this video showed me some things I did wrong but will do better if I ever plan to get another rainbow shark in the future.

[@dscott7864]

This is an awesome video. I just bought a rainbow shark yesterday. Its new home is a 55 gallon aquarium with tank makes, including 8 black mollies, 7 cherry barbs, 6 giant danios, 5 silver dollars, 5 cory catfish, 3 firemouth cichlids, 1 three spot gourami and 1 opaline gourami.

[@christiancollier4126]

That's way too many fish for a 55 gallon.

Thank you for this wonderful tutorial! I got into fishkeeping a couple years ago, and recently my boyfriend was also bit by the bug. He really wants the Rainbow Shark so this video was a great intro. Completely unrelated question--how does one find a table strong enough to hold a 75 gallon tank? I have a 30 gallon right now but I know at 75 gallon would be too much. Any recs?

[@DilettanteCulture]

I have personally built my own out of 2x4s. It's very easy!

[@chrishifter]

I know this is late but legit any decent dresser or table will hold that just measure the dimensions

[@MrDuckWeather]

Hi from Australia. I have 3 rainbow sharks. One is the older adult [12 years old] and the other two are 3 years old. They are beautiful fish, who live in a colony with black widow tetras and a few danios. I didn't know that they may generally live to up to and around 8 years of age. My older rainbow shark must be rather unique give his age? Is 12 years old exceptional or not surprising to you if they are kept in the ideal environment? I have only just come across your terrific videos ;)

[@finb9073]

@BayAreaAquatics hey man love your setup. I’ve recently got a young one. However there is Kuhli loaches and a bristlenose who are in the tank as well (66G) would they be an issue?

[@dmoore0079]

I currently have one in a community tank with blue gouramis and swordtails. It's definitely more aggressive than I expected, but the aggression is only occasional and is usually directed at the gouramis. Neither group seems to show any stress from the chasing.

[@dutchcanuck3102]

My gouramis never left my sword tails alone. Every once in a while, the rainbow would get sick of it and go after the gouramis.

[@KissofKatholic]

Hi! I've recently grown interested in the aquascaping hobby and I was even more recently given an adult red finned shark by a friend of mine looking to rehome him. She had been keeping him in a 10 gal tank on his own and I upgraded him to a 40 gal as I did some research before bringing him home and learned that 10 gal was NOT sufficient. Here's my dilemma. I'm trying to figure out how to scape his tank and I don't know what kinds of plants/hardscape I should put in. I was leaning toward just rocks and plants, but seeing the wood in your shark tank has me thinking he'd be more comfortable with the extended range of cover. What would you recommend for low tech plants and appropriate hardscape for a 40 gal tank? Also, I'm not planning on putting more community fish in there with him necessarily, but I'm not opposed to it. If that was something possible given the tank size, and I decided to do so, what species('s) would you recommend and how many? I imagine they would need to be small and quick, but I'm still not terribly familiar with what are good species for these guys in community settings. He's shown aggression to my friend's community tank fish but i'm not sure how big that tank was or what fish they were. So they might've just been ill suited to each other. He's awfully shy and I'd like to create a more comfortable space for him and maybe entice him out with some quick fish to chase around if that's what it takes. Thank you for your advice in advance. I appreciate this chance to learn more about tank building and these amazingly beautiful fish. :)

[@aleyaartim3096]

I know it's probably late but still if you're interested I have kept them for 20yrs. My 10yr old current one is a bit shy and housed with a paradise fish male in a 42g tank. He likes to hide so i got 3 caves. Little plants and gravels. Driftwood I'd have had if I could procure one. I have kept them with bunch of honey gouramis/ pearl gouramis/ cherry barbs and mollies without problem. Now I spend less time on aquarium so keeping the bioload minimum. Other than that I'd say red-tail shark are more rambunctious than these. One thing you gotta make sure that the caves are big enough. Once I had to break the decor to get him out (no long-term harm done). They are pretty and sturdy fish. My favourite :)

[@samarcher6632]

i have a redtail shark quite small. and want to get a rainbow shark the same size. i was thinking if i get them when there both small that when there bigger they will get along. i also built two caves out of rocks one for each

Even large enough guppies will eat their fry when they can get their mouth around them. The rainbow shark would most definitely eat the fry, especially when it gets bigger.

Hi I just bought two baby rainbow sharks. I'm letting them grow up a bit in my 10 gallon with my 5 Glo Tetras and my 3 African dwarf frogs. Have had them for about 2 weeks they are doing great so far everyone is getting along. The plan is to put them in my 50 gallon tank with my 2 adult Silver dollars any my 1 African Clawed Frog. The aquarium store helped me pick this type of fish for my 50 gallon. What do you think?

Once they grow up one will chase the other down to death. Do your own research rather than relying on knowledge supplied by stores. Your store is shit.

So I have both and just noticed the two rainbow sharks fighting so I looked it up. I really wish they would have employees who know more about these things but I guess I should have done some research. Anyway, thanks for the information.

[@caileyvallone3377]

Shoulda gone with the Cory gang or an bristlenose pleco. They’ll get big enough (4-6 inches) to not be messed with by the turtle and are big eaters, if you’re worried about leftover food. Bn plecos love food. That being said, you could make very distinct territories and break up lines of sight with decorations to lessen aggression. Best of luck if it’s two males.

[@jodievans1484]

Was worried that the barbs might nip the shark... but surprised, they're actually afraid of him! The shark has claimed a part of the aquarium as it's territory. Would have liked to add more rainbows to the tank, but I heard this type of fish does not like company of it's own kind.

[@caileyvallone3377]

1200 gallons? That’s the absolute dream. Don’t add anymore ‘sharks’ or highly territorial fish. You can add another pleco, a new kind of barb or tetra. I’m a little bit curious if female bettas would be okay with them, tbh. My rainbow has his Spot in a sand cave under a decoration. Picked it within 10 minutes of settling into the tank lol. And bettas are mostly mid/top water... hmm

As for adding other barbs, yeah, just waiting for the petshop to have albino barbs. On putting female Bettas with Rainbows, sorry I have no idea, never done that.

[@FreshwaterIchthyology]

It's good you mention that their territorial specifically with fish with a similar morphology. I can't imagine bala/silver sharks being an issue to be honest specifically more mature individuals as their quite different appearances and the adults do reach some size, I was donated one adult individual and it's quite some size. I've been tempted for a while to take in an adult unwanted shark, particularly the red tailed black shark, Epalzeorhynchos bicolor but as that species is critically endangered and for a while presumed extinct I don't really want to fund them being brought into stores.

The red-tailed black sharks seen in the aquarium trade today are all captive bred.

Do rainbow sharks like to hide?? I just bought one in my 55 gallon tank and I a bit of little caves and plants 🌱 but I put it in and now I don’t see it nowhere I even lifted the things to check if it was still there and nothing . Can you guys help I’m getting a bit worried I just bought it.

[@DilettanteCulture]

Yes they do. Especially at first. As they get comfortable (and bigger) they will come out more and more.

Bay Area Aquatics thank you 🙏, I was about to panic start taking everything out I was like we’re is my fish 🐠 I don’t see it anywhere.

Always keep a lid on. They like to jump when in a new tank

mine has claimed the filter as it's territory. It hides there, but comes out in the morning to feed when I give food to the tiger barbs. My Rainbow shark has got fat already.
