cory cat

I changed the substrate yesterday to sand to help keep my Cory’s safe and when I returned them back from the holding tank that had their tank water in it, one of my baby Cory’s eye looks really bad. I put some melafix in the tank but I think he’s be happier in the big tank than moving him to a...

Hello all! I've been keeping pygmy corydoras for a few years because they are my favorite fish. I'd really like to see them reproduce but they don't seem to be doing so on their own. So what I'll do here is go through some of the steps I've been taking to get them to spawn and hopefully one of...

Hey there, Unfortunately, we have a larger problem. The smaller fish that I thought was being "roughed" up is very red. I was repeating water changes and he seemed to improve. But now he has regressed and our other fish are showing red marks and flashing. I am really concerned as I can't find a...

Questions regarding my two tanks, my 10 gallon and 30 gallon. I pictured my 30 gallon... I'm working on both. Sorry it's a lot! 1) Can cory cats and oto cats live together? I have two young panda corys and an old bronze cory cat in my 10 gallon, the old cory is kind of a fat bully who muscles...

in my tank i have 8 cory cats and a betta. one of my cory cats suddenly started like only swimming at the top. i mean like it has not left the top of the water since 6pm last night (it's 9am rn). whenever it tried to swim down, it just floats up again. i'm gonna attach some pics becuase you cant...

So, I've got a 29g tank, already running for 4 months. Couple of months ago I bought a dozen neon tetras and within 2 days 5 died. Columnaris, NTD, or too much stress, never found out for sure. Fast forward to yesterday. I've had a planted and cycled "quarantine" tank running for 3 weeks now...

I absolutely hate to think this but I honestly don’t know what else to do anymore besides just start over. I’ve made a lot of mistakes and really think they’re suffering for it and at this point, I don’t know what to do anymore. My only main problem rn is that I just don’t know how to go about...

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...

Okay, so I’ve had a small 5 gal with glofish for years, and I upgraded to a 15 not too long ago. Maybe a month ish? I let it sit with plants and filter for a while before acclimating the 4 glo tetras I had into it (plus some snails), and about a week ago I got another tetra and 5 cory cats. I...

Hey guys, I hope I'm right posting this here.. My situation is following: I have had my tank (15 gallon, planted, no CO2, 3 pepper corys with 1-2 more to come, 6 amano shrimps) for about a year now without a problem. Ive been away once on business for 10 days and a friend took care of my tank...

Hi, One of my cory catfish has swim bladder disease, so I just went out and bought a medication However, it says that it can't be used for scaleless fish. I know corys have "plates" instead of scales, so would it still be safe to use? Thanks very much, any help would be appreciated

I just got 2 new luxozonas cory cats. One of them is doing great and the other was rough from the start. He swam through some bubbles and looked a little wobbly. Then he was just laying on the bottom. After a while I noticed him having a hard time keeping himself straight. Eventually he was...

One of my four Cory catfish has suddenly gone pale and very inactive in the past week and isn’t eating now any help with this would be appreciated. My tank is 54 litres with 5 neon tetras, 1 guppy and 4 Cory catfish. And the tank stats are 0 ammonia, 0 nitrite and 10 nitrate.

Hello everyone. Can anyone help me here please. Today i noticed that after, a bit more than a year, and everything has been fine, one of my Corys have something on the side, almost like if he scratched with something or crashed with something and got hurt. But im not sure how something like this...

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...

So I have way over stocked my tank and I'm looking to get a new one. I have 2 angelfish, 3 dwarf gourami, 2 mollies, 4 platies, 10 neon tetras, 4 cories, 4 algae eaters, 4 danios, and 3 snails. I had 20 ghost shrimp but I'm pretty sure they got ate by my other fish as there's no bodies from...

Hi, everyone. can I take beach sand for example and just boil it to kill any microbes and bacteria in it or should I buy purpose-made sand substrates? I am in need of a sandy bottom in my big tank for barbs like corys.

I’m thinking about adding a Dwarf Mexican Crayfish to my established 20 tall killifish and Cory tank. I’ve seen conflicting opinions on whether the crayfish will harass/eat the corys. I have 4 albino corys, 2 emerald. Is this a feasible combination or should I just skip out on the crayfish? I...

Hello all! 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 brand new 65gallon deep set up...

I have a 65 gallon deeper than it is long. Said tank is my pfp. How many angels can I keep in this tank? Tank is planted and has a fairly decent sized driftwood. We have some Cory cats already (about 20) as tank mates. And plan to possibly add some schooling types as well, maybe cardinal tetras...

I have a 7lb manzanita driftwood that I’m waiting to become waterlogged and sink. Anyone with a similar wood size and type that’s gone through this before? Any guesses on how long? Everything I’ve been reading online has been all over the place as far as how long it should take. It has been 1...

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...

I recently got 6 pygmy copycats for my big tank and when they were in a qt tank by themselves I fell even more in love lol. But now they are in the big tank with platys swordtail and bronze Cory's, I don't see them shoaling like they did as much. They're behaving fine, not seeming scared of the...

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...

I noticed some white starting to appear on some of my bronze corydoras fins, and I cant quite figure out what it is. One cory has it worse than the rest, and it looks as if the fin is actually beginning to rot away. I've had these cory for over six months now, and I've owned cory for about four...

Hello all! I’m relatively new to fish keeping but I love it so much! I got some new corys yesterday and I was wondering if anyone could help to identify their sexes if possible! Here are the two Juliis. I think the one in the back is female and the one in front male? (guessing! lol) Here’s...

Intro: Hi everyone thank you for taking the time to read my first post. This isn't my first forum experience and I am well aware of the search function. However I wanted to post this asap and hopefully someone can help me faster then me looking for the answer. The problem: I noticed a...

Ive recently got my 125 and it currently going through its FISHLESS cycle and im really struggling with ideas on what to eventually stock it with. I love all sorts of fish ive looked and and researched and the only one i have decided on is the black corydoras. So what do you guys reccommend...

Hi everyone, We have a 125 L (30ish gallon) tank with 3 Swordtails and 7 Corydoras Sterbai. The corys have always seemd pretty happy, and they have occasionally layed eggs. We have a few, now. But they never seem to survive. Is there anything I can do to protect the eggs/fry? Can the eggs...

Ok, first off is it ‘corys’ ‘cories’ or ‘corries’ when discussing multiple corydoras??? My websearches have been conflicting and I’m curious if there’s a generally accepted ‘correct’ way? Secondly- what is the ideal tank alkalinity for these little guys? I haven’t found a concrete answer for...

Hi, I currently have a 10 gallon tank with some green and peppered cory catfish in it. One of the peppered cory cats looks very skinny to me compared to the others. It’s a little less active, but still more or less acting normal. I’m worried it’s in the early stages of some kind of disease, am...

Hi, I’m new to this forum this is my first thread so I’m sorry if I’m doing this wrong, hopefully you guys can help and I’ll learn along the way. Anyways, I recently noticed my peppered Cory cat chasing around the largest fish in my tank which is my female black molly. It doesn’t seem to be...

I really want some flag-tailed panda cory but am really struggling, does anyone know of where I can get some or even an importer from Brazil I could contact please. Would be really grateful

Can anyone tell me what species this Cory is? I had always thought he was a Julii or Trilineatus but he lacks that characteristic mid-body stripe. Thanks for the help.

Ok so after a very long time I finally got back into the fish hobby I got myself a 40g acrylic filled it with plants, cycled it, had my water tested and all my fish are happy and healthy..... except for any bottom feeders I add... Death count 2 green corys, 1 bristle nose pleco, 1 clown pleco...

Hello all! While I'm not *exactly* new to the hobby, after doing a lot of reading I've discovered that I'm new to keeping fish correctly (as in, all those years I was keeping fish as a child, I was basically running to the pet store, thinking 'this is pretty,' and getting extremely lucky that...

Hi everyone, My name is Skye Phan. I have a 50 gallon tank with 3 medium size bala sharks, a 5" common pleco, a 2" albino bristlenose pleco, 5 longfin zera danios, 4 neon tetras (I had nine, but they have neon tetra disease. I am hoping to replace these with more danios), 6 albino cory catfish...

hello, I have 4 corydoras for some time now and i bought them all from the same local fish store. He only had 4 bronze corys at that time. In the beginning everything looked ok. There was just that one guy/girl that looked a bit funny. The difference with the other wasn't that big and he looked...

Hello I have a 20gallon tank with: 4 corydoras aeneus 7 guppy 2 platy 3 upside down catfish And I noticed a problem while feeding. The guppys and platys are always eating the food of my corys. To help the corys I try to distract the others with flake food on one side of the tank while I sneak...
