Corydoras Tank Mates: 7 Fish You Can Keep with Corydoras

In today’s video we’re going to be doing the top seven tank mates for Corydoras now. Corydoras is a bit of an interesting fish because normally you’re not going to suggest tank mates for the Corydoras, you’re going to use the Corydora as a tank mate for other fish. Basically, in today’s video we’re going to kind of like switch around the situation a little bit and suggest some tank mates for the koiori.

The Corydoras is a really good community fish. It’s kept with a bunch of different types of fish because they stay relatively small. They are also very peaceful, they’re not aggressive at all, and they also stand on the bottom of the aquarium so they’re out of the way of most of the fish that we keep in our aquariums. Today I’m going to give you seven of the ideas and things that I would keep with Corydoras and I’ve kept with Corydoras and basically just give you some of the ideas that I would use in my aquarium so make sure you stay around.

Rainbow Fish

Number seven on my list is gonna be the rainbow fish. Now, I’m gonna be talking about pretty much all kinds of rainbow fish. Obviously, there’re some that get like a little bit bigger. You’re going to want to house them in like a bigger aquarium, but the reason I say this is rainbow fish. First of all, look amazing, there’s a bunch of different types that you can get. They are from the regions that I’m in, so like in the Australian new guinea region. They just look really cool, they’re, really peaceful and they school.

Personally, I tend to go towards more of the dwarf neon rainbows, but there’s also the bose minings, which I absolutely love. There’re turquoise rainbows, there’s just like a ton that you guys can choose from. The best thing about these guys is they stay up on the top of the aquarium, so they’re not going to get in the way of the Corydoras.

They both eat kind of the same foods. So if you chuck some flakes in the aquarium, you’re gonna get your rainbows eating it and then they’re gonna fall to the bottom, and the Corydoras can finish them up. The best thing about these guys too is they have relatively similar water conditions. These guys like a bit more harder water, the quarry always like a bit soft water, but they can bear with that 7.5 ph, if you keep them in those water parameters, then you tend to have quite a bit of success.

So, they’re really good fish. You can also easily breed them, just chuck a spawning mop in there and you can make a ton of babies.


Some cons about these fish is in some areas that can be relatively expensive and also they’re not like a super good beginner fish. They’re kind of more of an intermediate style of fish. So for all the beginners out there maybe try and stick to something else before you try these fish, because they are prone to quite a few fluctuations in the water and some of those beginner mistakes that you are kind of destined to make.


Number six on my list is going to be angelfish. So, angelfish are like really near and dear to my heart. I’ve had them pretty much the whole time. I’ve been keeping aquariums not like the whole time. I got them like after I’d had live bears and stuff like that, but the reason I love them is, first of all, I breed them. I’ve been breeding up a storm there’s, so many of these guys that I’ve made and the other reason is they just look absolutely beautiful.

There’s not really any fish that look like the angelfish and they are a pretty interesting fish. These guys have a really good relationship with each other, the Corydoras and the angelfish. The Corydoras are obviously gonna stay along the bottom and angelfish will stay at the top. They’re not gonna really have much to do with each other, but also what’s gonna happen is when you feed your angelfish there’s going to be food that falls down to the bottom, that the Corydoras can clean up and they just really work well together.

The best thing about Corydoras is they have like that armored top on them. So, even if there’s some aggression from the angelfish first of all, the ant fish kind of like don’t really go for them because they’re down the bottom, but even if there was the Corydoras are already like really protected. So, they really do work well together and there’s a bunch of different types of angelfish. You can get so they’re, not like the easiest fish to breathe. They can be relatively easy if you get like a pair, but overall they just are really personable fish and they’re really good for beginners because they are super hardy.


Number five on my list is going to be bristlenose. So the reason I say bristlenose is these guys kind of work together a bit as a cleanup crew. I don’t really like using that term. I don’t ever treat fishes like cleaner fish, but these guys are notoriously known for going along the surfaces of things in the aquarium and cleaning up like that dust, green algae kind of stuff. They really just absolutely love it. These guys don’t eat like all kinds of algae. They’re not like an algae, eater fish. The best thing about bristolnose is they keep the glass pretty clean and you don’t have to like constantly scrub, because these guys do a really good job of cleaning that but the worst thing about these guys is they create like a lot of waste.

So, they work together because the Corydoras kind of pick up like all the bits of food down the bottom and stop them from rotting and then the bristlenose also help with cleaning up the glass and stuff like that. So, they’re really beneficial in that matter. One of the mistakes I haven’t really talked about much on this channel and something I kind of needed to address in this video is a lot of people don’t realize that they have to give bristlenose like proper aquarium food like an algae, wafer and zucchinis and stuff.

They think that they just eat the algae and that’s just simply not the truth, so make sure you’re actually gonna get something to feed these guys. When you get them be aware, they do create a lot of waste, but they are super peaceful they’re. Not gonna go after any fish in your aquarium. They’re not gonna attack any fish. I always hear people saying these guys killed my fish. Normally, what’s happened is your fish has died and the bristlenose is just you know like having a bit of a meal.

So basically, these guys are super good. If you have a cave in the aquarium, when these guys get a bit older, if you have a male and a female they’re definitely going to start breeding. Definitely one of the best tank mates for your Corydora.

Celestial Pearl Danios

Number four on my list is going to be celestial pearl danios. The reason I say these guys, instead of like your classic just zebra, danios or leopard danios, is because these guys look like a little mini trout. They are a super cool shoaling fish. They’re not like a great schooling fish. They kind of just sit as a group in the aquarium. They are a really good tank mate for the Corydoras, because, first of all, they’re so tiny, so they can’t cause any aggression or anything like that, but they just work really well together.

These guys are super cute. They are one of like the best looking micro rasbora fish that I’ve ever seen like these guys are incredible. The cons to these guys is they can tend to be like the tiniest bit more finicky than like your danios and stuff like that. But again, they are very easy to take care of the other. The problem with these guys is they also can cost a little bit more than like your zebra, downers and stuff like that. But if you’ve got like a 20-gallon aquarium, pick up like eight of these guys put them in there and you’re just gonna have a really cool display.

These guys aren’t gonna breed easily for you in the aquarium like guppies and stuff, would but they’re gonna just constantly be swimming around the aquarium and just providing a really cool display. I absolutely love these little guys.

Dwarf Cichlids

Number three on my list is going to be dwarf cichlids. So I’m all talking about your south American dwarf cichlids. I’m not talking about like crabbiness and stuff, like that. You can keep provinces with these guys. But the reason I say your dwarf cichlids from south America is because these guys share the same water as the Corydoras. So, they first of all come from like the same part of the world. So, they have very, very similar habitats that they need and care kind of conditions as the Corydora is, and the other reason is these guys are like a really cool centerpiece fish they have.

This amazing display, there’s all kinds of different styles you can get. There’re plenty of different types of south American dwarf cichlids that you can get. You can get rams and stuff like that, and basically these guys just have really outstanding displays and you can get like a pair of these guys in the 20 gallon aquarium, with a couple of little Corydoras around and they’re just going to act as really cool like Puppy dogs in your aquarium – I absolutely love these guys.

I’ve been breeding a ton of apistogrammers lately and they are super fun fish to keep. They can be a little bit more aggressive, but I tend to not see these guys going after my Corydoras. Nonetheless, they are really good tank mates for these guys.

Number two on my list is going to be endlers. So endlers are kind of like one of the best tank mates for a lot of really peaceful community fish, but especially these guys. First of all, these guys stay really small. There’s a ton of different types you can get. Breeders have done a really good job of making sure that you guys have tons and tons of different analysts to choose from they’ve got insane colors.

These guys look really vivid and the best thing about these guys is they stay small, so they get like either one or two trios of these guys get like one or two males and then like four females and they’re gonna breed up a storm and the best thing about these guys is they’re not like the guppies, they’re not like super inbred. I’ve like tended to notice that these guys have less issues when they’re breeding, so there’s less bent spines and overall, they kind of are more hearty a fish. So, they’re definitely one of the best beginner fish and if you guys are like brand new to the hobby, pick up endlers because on this list this is going to be like the easiest fish to take care of.

I absolutely love these guys. I’ve been keeping them for quite a long time – and I’ve got this green tank down here – it’s just absolutely full of endlers in there. So I’ve got blue star endlers. They look really cool, but there’s obviously like tons and tons of these guys to choose from so. These guys are a really good tank mate for your Corydoras.

Smaller Tetras

Number one on my list is going to be kind of like a broad category of fish, and this is going to be a smaller tetras. So I’m talking about neon tetras and your green neon tetras. Those are like my favorite small tetras to add to a Corydora tank because corydoras have like that iridescent display on them, especially your green lasers and stuff, like that. Even your bronze and albinos kind of have that display these neon tetras all kind of come together really well with those displays in an aquarium.

So basically, what I’d recommend to do is get a 20 gallon aquarium. I’d get like 10 or 15 of these guys and basically just put them in there and create like this beautiful display, because basically, a planted aquarium with neon tetras is like a guaranteed good-looking display aquarium. They’re not going to be easy to breed for you, but they are going to really go and look nice and aquarium and the best thing about them is these guys stay at the top of the aquarium, so they have absolutely nothing to do with the Corydoras down the bottom – and they just really have this really cool relationship with each other, and it just works really well.

Another really good thing about these guys is they come from obviously the same part of the world as the Corydora, so we have that same kind of care and water parameters. There’s like a bunch of different types. You can get bigger tetras, but there’s not a lot of fish that you can keep small touches with, but Corydoras are definitely one of the best to do it with. So that’s why I say small tetras.
