corydora

Can someone tell me which are male and female Corys? Thanks in advance. Pictures in attachments.

Long time no see! I found an unknown mussel on a driftwood piece that hasn't moved in over 2 years, until today. Background on tank(s). I was tearing down my 20g long and transferring all of my livestock, plants, and decorations into my 29 gallon. The 20g was in rough shape and kinda...

Hello all, I am planning on getting a 50L / 13.5g aquarium, though i am stuck on how many fish to get. I am interested in a Honey dwarf gourami, a school of corydoras, and/or a school of some kind of tetra. What are you guys' suggestions? Gourami and tetras, cory and tetras, or cory and...

I've just recently got back into fish, and run into an old problem I've always had from my 20 gal to my 40 gal breeder. Tank has been up and cycled for years, just haven't been replacing fish until it got to the lone cory. I currently have a 20 gallon with 6 albino corys, 5 guppies, and a bamboo...

Tried to get a few videos of my tank, unfortunately the cories were nowhere to be seen so its mainly a video of my frogs and snails hanging out at the top! Tank has been set up for 2 months and I'm happy with how it's going although will be happier when the plants grow in a bit more.

Panda cory has no tail Very small panda cory has lost its tail along the way more then likely due to tiger barbs Is there any hope for him or more then likely not Have him isolated as of now in a breeder box ad I don't have another tank as of now As you can hopefully see it is still alive

Hey, I am new to fish keeping. One of my Corydoras got bloated lately. I thought it was about to lay eggs, then I read about different health conditions incl. constipation, bloat, and dropsy which may be the case here. Also noticed that Cory's color got lighter as well (FYI two other Corydoras...

Hi, 2 days ago I got some peppered corydoras - one of them died before I even got to drop acclimate them. The other two are doing well in the tank. I called pets at home and they said I could come get a new cory. I’ve just brought him home today and noticed his fins are a bit ‘teared’ ? Not sure...

Hi there everyone, I just have a situation happening with my corydora. For the past week one of my corydora has been struggling to swim and cannot control its body movements. It will try and swim and will just fall on its back or side and stay there before trying again. Obviously my biggest...

Woke up to one of my female cories dead at the bottom of the tank. As the pictures might show she had the bent spine that seems common on these when overbred/inbreeding, but she was always pretty active and healthy looking, up to last night on my last glance at the tank all the fish were acting...

I noticed a couple of days ago that my big female bronze cory was panting. Normally they move their mouth/gills when eating food, but she does this constantly now and has never shown this behavior before. Other than her mouth/gills moving rapidly, she also goes up for air a bit more than usual-...

I'm currently setting up a low tech 55g aquarium and I'm having trouble with the substrate. To cut to the chase, I'm looking for a black sand that won't be harsh on the cories and other bottom dwellers, but will also be a practical substrate for plants without too much extra care. I've heard...

We got 3 corydoras at the same time and they were all the same size but one of them is now much bigger than the other two? Does anyone know why and should we be worried? (We have 6corydoras now) Thanks x

Found these while doing a water change on my cory tank. They were stuck to the side of the filter inlet pipe. There's only corydoras, a couple female guppies and my male bristlenose pleco in the tank. Could they be cory eggs? If so, how do I successfully hatch and raise them?

Hi, new fish keeper here. I have a group of six peppered cories in a 12 gal planted aquarium with some guppy fry. Had three to begin with and recently added another three to the group. One of the new ones has a bent spine and is behaving a bit odd. He is very inactive, but can swim ok when he...

I bought 5 albino corydoras yesterday and lost one on the same day plus two more this morning. they seemed to be perfectly heathy. I also have a betta in the tank with them, but I haven't seem him chasing any of them, and there was no phisical damage on the dead corys. My tank is cicled, about...

Hi all, I'm considering putting some Corydoras in my 200 L community tank as there are currently no bottom dwelling fish in there, however I heard sand or finer substrates are best for them. Will they be ok with my aquasoil substrate at the bottom? Or will this be harmful to them when digging...

Hi All, I'm thinking of getting the aquastyle 620 tank dimensions are 62cm W x 52cm H x 39cm D. It says the capacity is 90L but when I put it in to Aq advisor it says it's 120L and I'm mega confused. Would this stocking work? My tap water GH is 1-2 and PH is 7.56 - 8.01 2 Dwarf Gourami 6...

Hey guys i have 3 corydora catfish i have had for a while now and i have never had any issues with them. today when i got home from work i went to feed them and i noticed one was sorta laying on it’s side and wouldn’t move so i tried to pick him up with the net (i honestly wasn’t sure if it was...

Hello everyone! I'm not particularly stressed, but I'm just curious and slightly worried about one of my albino female corydoras. She had a red spot that faded to black on her egg area around a week ago, but it's completely gone now and she was lethargic for one day but instantly improved (it...

Hi there I'm originally English but I live in Denmark. I'm fairly new to the hobby - and I've gone ALL in ... within 5 months I've gone from 0 to 7 tanks (360L, 250L, 190L, 150L, 125L, 40L, 20L) and I'm planning on a rack system with 3 x 80L ... I have got the rack system and the aquariums, but...

I had an albino cory since i started my 5g with my betta about a year ago. Petstore said it was a good algae cleaner. I didnt know better. Since then i learned about groups. Finally saved for a bigger tank. Got a 20g. Lost my betta. It was just my cory, mystery snail, and some hitchhikers from...

Hi guys I'm new to the forums here. I had some casualties this week and I'm trying to figure things out :/ I purchased two of these little Julii cory cats from Petco the other day (they were fairly small, maybe half an inch) and they both died already! My aquarium is well established with no...

Hello! I'm new to fish keeping and have been doing my research for a couple of months. Got my tank ordered & done water checks. I'm after a bit of advice about what substrate is best for aquascaping as I'm very interested in this, but I'll also be getting some corydoras so I'll also need...

I am a very proud fish mom today! My corydoras have been spawning FOR THE VERY FIRST TIME EVER all day today!!!!! I've been able to save 11 of the eggs so far, but most burst when I tried to get them. I'm not sure if it's because I'm inexperienced but I tried to be gentle. I read that fertlizied...

Hey guys a few months ago i got 3 corydoras and they were doing well and swimming around, but recently one out of the 3 has been staying in the back corner of the tank all alone and won’t move. he definitely is alive because i kinda nudged him out of the corner with a net because i was worried...

I am new to the hobby and I was told my Corys will be happy as long as I get at least 4. I asked if they need to be the same species and I was told that they don’t, so I got two Julli and two Peppered Corys. BUT I have been reading that they will not technically school together. They seem to be...

My sister has a freshwater tank and was wanting to treat her betta who has finrot so I recommended aquarium salt in a water change. Unfortunately in the water change she forgot to include the stress coat water conditioner. This means she put in a water change of unconditioned water treated with...

Hi, I'm new to fishkeeping and have been loving it, however I am worried about one of my Corys. I have 3 in a 57 litre (12.5g) tank along with 6 neon tetras, 4 danios and a dwarf gouramis. A few weeks ago the smallest Cory disappeared and I couldn't find him. A few days later I found him stuck...

First off - I apologize as this will probably be a novel. Can anyone help me ID what killed my albino corydora? I've had two for over a year (which I know they need more friends, but I didn't have tank space until very recently and haven't even had a chance to increase their school size), and...

Sorry if this is the wrong place to post this question, i'm not new to fish keeping, but I'm very new to keeping my own fish tank and species other than goldfish. My family has had goldfish for 15 years or thereabouts, so since I was 4, and currently we have a 13 year old and 3 year old goldfish...

Moved over from the introduction thread... I’m excited to be here. I have some experience with basic tanks in the past; betas, guppies, mollies, etc in 40gal or smaller. Nothing this big or beautiful until now. Most recently I deactivated my Facebook account and decided to go all out with a...

So I grabbed the last 3 of them from the LFS. And they were obviously not albinos though labeled as such the worker at the time sold them to me as albinos since he did not know what they were. This was a couple of years ago and 2 have died I want to get him a group but have not seen any like him...

Hey all, I have a 29 gallon tank that is super close to finishing its cycle (thanks @mbsqw1d). I have 4 corydoras paleatus, and will be looking to get 4 more. Would I be able to stock a Blue Acara? If not is there any cichlids I could stock? Thanks!

Hey all, I don't know if this is good or bad news. My friends tank was leaking, but he had a backup 20 long. This was a 29 gallon tank. He needed me to take care of 4 of his Peppered Corydoras. As you know my tank is relatively new and the plants have just started growing. I acclimated them for...

Can anyone tell me what these are. fish eggs or java fern related. thanks 120lit 0 amm 0 nitrites 5-10nitrates kh& gh is fine ph 7.4 stock is 7 corydoras, 1 bristlenose, 7 rummynose, 2 zebra nerites, 6 cherry shrimp

I've already lost one Cory to this and I don't want to lose another, hoping someone can help. I got these 2 at the same time a while ago and got an extra 4 more recently. Basically, both of the older corys had what I assumed to be swim bladder issues since they were using leaves to avoid...

Hi all, This is our first post here. I purchased some corydoras about 7 months ago and within a couple of days, one of the corys started developing these lumps. At first they looked like fungal infections. They were fuzzy/fluffy looking. They grew quickly and then stopped. The lump on her side...

In my circus of an apartment I have several small and medium tanks. This will be a collection of pics of my tanks and fish. This first one is of the fish in my "Red" tank. It has cherry shrimp, ember tetra, a female betta, and temporarily some pygmy corydoras.

Ok so my corydoras have gotten these white spots and have had them for about a week but I haven't seen any major outbreak in my tank/ no white spots on any of my guppies and the specs have been limited to only a few corys, the white dots kinda seem to be off and on because i saw one cory with a...
