Is it possible for a corydoras to lay TOO many eggs?

Madame Chungus, the cory that was a whole BAKERY (I showed her a couple days ago! With her PHAT booty) is.... erm. Extremely fertile today. She laid so many eggs that she kinda looks like a pencil compared to before. She even has sagging skin, the poor girl. She's been ''talking'' to me like I showed before as well, that's when she starts to get tired but her body tells her to keep going. Is it possible for a cory to be TOO fertile or lay TOO many eggs in a spawning session? I'm not overly worried about her but I just know she's uncomfortable after a while.

Miss Chungus ''chungusing'' to me for tax!

She was doing her Chungus dance and ''talking'' to me in this pic!

Panda Cory’s schooling and enjoying the new tank!

There’s a sixth but it’s hiding. I’m loving these little guys so far. They’re sharing a ten gallon with a nerite and a few ghost shrimp. Planning on adding some danio margaritatus soon.

So I'm moving the fish to their new, bigger digs

And LOOK WHO I FIND.

Pardon the yellow water. Old tank had a lot of leaf litter (inherited it that way) so it was pretty brown from the tannins. New tank doesn't.

Now I'm trying to decide if I should let him go first and hope he finds a hiding spot before I let the big fish go, or go to the pet store an hour away to get a breeder box until he's too big to eat.

Day 4950346 of waiting for Peppiemint to spawn soi they can be confirmed male or female...

Look at Pep. They don't care that they're apparently unsexable. They just want shrimp and a nap. Had to draw a crown on them

Eggs again..

We had our peppered mama lay eggs 4 weeks ago! Then our albino went crazy but ate all eggs but 1! Yesterday I come home from work and we have 45 more eggs. But I'm not sure who the mama is at this point!

New shoal of brochis splendens

I got 8 emerald corys from Bob's Cory Castle, and OMG how is it that I never realized how huge they are! I have them in an over-filtered 22 gallon bookshelf tank. I imagined a happy little blundering group like my pandas. So far, the emeralds have dug themselves a little bunker under a piece of driftwood and are huddled up there, glaring at me. I tried squirting some live daphnia at them and that got some activity, but not for long. I know the tank is not over stocked. I chose this tank because it's 36 inches long, giving them some swim room. How long should I wait before giving up and re-homing them?

Mixing cory species?

So today I lost my 2nd cory. The group (added on 3/20) was originally 7; I lost the first within a few days and then this one today. None of my other corys (or tetras) show any of the indications of the one I just lost (whole tank was dosed with API General Cure).

So now my school is down to 5. I’m thinking of getting 3 more of the same type to bring the school size back up. Hubby says to add 5 more of a different type of cory (the type I initially was looking for).

Suggestions/thoughts welcomed please!

What’s this, some kind of Cory gang initiation?

My apologies about the quality of the video and Tomahawk trying to steal the show… I just rescued a panda Cory from a very poorly kept Petco tank all by their lonesome, and despite already having 8 other Cories including another panda Cory, this Juliee started pressing the new member? Never seen them do this was this joy? Territorial stance? Or something else?

Help confirm sex

I wanna maybe try and breed some of my bronze corys, I’m pretty sure I have a male and female but I would appreciate some other thoughts, too one I think is male and bottom I think is female. (I have them separated until I confirm sex)

Panda with a fuzzy patch on his fin.. tagged NSFW and spoiler if you don't want to see a sick fishy

Hi corydoras lovers!

I'm in need of help. One of my pandas has been sick for a week now. What started as a little white patch on his fin now looks like a big brown fuzzy patch after a round of esha 2000 followed by a first round of Sera Baktopur treatment. Tomorrow would be the end of his treatment.

You can see the patch in the video.

Has anyone ever experienced this? Did the patch fall off? Did it propagate to the body of your fish?

He was really lethargic when I first found out he was sick, but is now acting a lot better in his hospital tank (dancing, foraging, going for air gulps as normal..)

It's breaking my heart to see him all alone and I really hope he is going to make it.. Let me know if any of you have seen anything like this and if something worked out well to get it healed!

Thank you from me and Johnny Barbillon (French for "barbels"

Anyone else’s derps do this???

I can assure you he is most definitely alive - he’s been doing this since he’s hatched a little over a month or so ago. Literally as soon as I snapped this he flipped back over and took off.. he also likes to do this same exact thing up at the surface of the water. Idk if he’s just dumb (possible 😂) or if he just prefers to sleep that way but he gives me a mini heartattack every day when I get home from work cuz I think he’s dead until he sees me cone near the tank and zips off. 😑🤨

Also - ignore the bladder snail infestation. Bought a plant from the lps and boom - infested. 😒😠 trying to figure out how to get rid of them without hurting anything else in the tank & I’m hesitant too bc cory babies.

Quarantining cories, or trying to

I got a batch of albino bronze cories at a local fish shop last week and I’ve been quarantining them in a 5-gal bucket. It isn’t the full 5 gallons of water because one of the cories has been having weird breathing issues, so I’ve got very low doses of Kaniplex and Prazipro in there. I so far I’ve changed half the water every two days, and replenish some of the meds after the other half is changed and so on. I’m trying not to do too much, since the Prazipro says not to repeat a dose until a minimum of 3 days.

I know they’re still new, but they look kind of rough. The one that was seemingly having breathing problems was at the water surface a lot in the store, and I tried asking staff to avoid it, but with all the fish in a frenzy from the net I got it by accident. It’s very skinny, drained color, and now it’s suddenly lethargic, barely responding to stimuli and not searching for food. Now this morning I saw a cory flashing—I know flashing here and there can just mean scratching an itch, but I’m worried all of the cories have some parasite. I’m hoping if it’s something like flukes the Prazipro will get it in time, but if it’s ich I don’t know if I’m supposed to combine copper and Prazi even as quarantine meds? I definitely don’t want to overdo the medicine in general so I don’t overload their little bodies.

(My goal is to eventually move them into my planted 20-gal with a lonely cory who is waiting patiently after becoming a sole survivor.)

Does anyone else’s Cory fish look at you most of the time when I’m looking or just glancing at the tank?

Adding young False Julii Corydoras?

(Sorry this is a long read, questions are at the end!) I got totally mixed opinions on my Julii vs False Julii post a couple days ago, but I did officially conclude that I need to give these two dudes some friends. A little backstory: I've had these two Julii and/or False Julii Corydoras for a couple of years now, they were recommended to me as "good tank cleaners," and I'm sorry to admit that they were an afterthought at the time -- I really had just been looking for something to help keep the tank clean for my frogs. Anyway, I really like these bumbling little fish and have been doing a lot of research lately and want to improve their quality of life. As it is, this (see picture, you can see a tail and a face) is pretty much all I see of them, for the last two years. One of them comes out quite a bit more, but tends to be skittish. The other is almost always in the log. Water parameters are good and monitored regularly, substrate is fine sand with large pebbles here and there. Tank size is 20 gallon long. Tank mates: 3 constantly humping African Dwarf Frogs, 4 Panda Corydoras, 2 nerites, and some rando hitchhiking ramshorn that is hopefully not laying eggs all over my tank. None are the least bit aggressive (other than the frogs and their raucous love making!) Anyway, I understand that shoals of 6 are preferable, but I am nervous about overstocking. The 4 pandas seem happy, life is just one big rave for them. But the Juliis... 😬 I always felt like they weren't very active, and now I'm learning that's because they're bummed out and lonely all the time!

So to finally get to my actual questions...

  1. Would getting 4 more Juliis/false juliis be too much for this size tank, or should I just get two more? AqAdvisor seemed to think I could get 4 juliis, 2 more pandas, and even another frog and have room to spare, but that seems like a lot, doesn't it???

  2. If I do indeed have one false julii and one julii, are they close enough that they'll mix and school?

  3. And lastly, what I'm actually most curious about -- will these older, bigger, apparently sadder fish join in and swim around with the smaller, less jaded youngsters? Or will they just continue hiding all the time? They truly do not get out much...

One of my cories is blowing bubbles

One of my albino cories is blowing bubbles at the top of the tank, near the side wall furthest away from the tank equipment. I have a large air stone, and a waterfall filter to make sure the water is oxygenated. The other two cories are behaving as normal. Any ideas of what this behavior could be?
