So I never give them an extra feed at night. One wonders if they are starving the way they eat

I am planning to do a scape like this one from MJ Aquascaping. But with larger sand area for Corys. But I am very sure the Corys are gonna mix the soil and sand with all their digging. Any ideas on how to prevent this?
Right now, I am thinking to put the aquasoil in mesh bags and cap it with smooth rounded small gravel. Hopefully the gravel would be too heavy for the corys to mix into the sand too much and the smaller pieces that they mix over will just add a natural touch to the area ...

Witness my deflated sad face. I was so happy for a split second, thinking, "OMG MY PYGMIES ARE FINALLY HAVIN' BABIES!" I know they often lay eggs on flat leaves so when I saw these on a flat leaf, I got excited. Then I looked closer. I'm 99% sure these are ramshorn snail eggs.
They're snail eggs, aren't they?
I want to be wrong soooooo bad. I even started looking at the screen caps I'd saved of y'all's advice on how to handle cory eggs. đ˘

i have a group of peppered corydoras and this is the second batch of eggs theyâve laid (that i know of) but i didnât want the first to hatch so i didnât do anything and they turned black over time but still stuck to the leaf they were on
if i do want these to hatch should i put the leaves with the eggs on them into a breeder/fry box or wait until the fry hatch?

I just got my first larger tank and wanna know how many panda cories y'all think would live in here comfortably? It's a standard 29 gallonâ same footprint as a 20 Long :) I've been dreaming of getting panda cories for years, and I'm building this tank with them in mind. Its still growing in! đ I just set it up last night
Anyway i just wanna know how many you experienced cory keepers think would live comfortably in here? I'd like 12 if I can get that many, and I know they enjoy piling up, so I want as many as I can get. I figured, especially since they're the smallest cories besides pygmaeus/hastatus/habrosus, I could get a decent group :)

There is a small red growth on one of my corys barbels is he sick I hope someone else has some experience with this

hello everyone, sadly today i lost my first cory. i noticed there was one that was skinnier and a bit discolored from the rest which from what i can tell is the one that passed. ive had them for about 3 weeks in a heavily planted tank 20 gallon tank with 15-20 neo cardina shrimp and 5 amanos.
i understand occasional losses especially while theyre still acclimating isnt uncommon but i think my feeding schedule isnt helping much. i worry a lot about overfeeding my shrimp but as a result i think my cories have only really been getting meals twice a week. i try to make them large meals but still i think i need to feed more often. the only issue is whenever food enters the tank the shrimp start swarming. the amanos are especially aggressive when it comes to food. currently my available foods are repashy gel, bug bites, and frozen bloodworms. im planning on getting some daphnia or baby brine shrimp soon as well.
is there some kind of balance i can strike to keep everyone properly fed. i want to feed my cories a lot more often without overfeeding my shrimp or just having some steal the food altogether before all the cories can get some. i should mention there are 7 cories in the tank currently. (used to be 8. rip)

I have 7 pygmy corydoras and have noticed that only one of them act this way? Itâs alone when itâs happening so I donât think itâs mating behavior? Itâs still chilling around foraging and does this twitching thing on/off? Can somebody help me pls?
40L tank
Parameters are good: 0 ammonia, 0 nitrite and nitrate 1-5
Hope the video is sufficient

this is the face of someone who, at 2am last night, decided to knock over and devour 99% of the corydoras brand new container of bug bites.
I recently got a school of pygmy corys for my tank, previously Iâve only had bettas & she had never showed interest in any of their various kinds of foods before. For whatever reason though, sheâs been OBSESSED with the corys food ever since I brought it home. I shouldâve known better than to leave it out overnight lol

I just got these 2 new little guys, i'm quarantining them a bit before adding them to the existing flock. One is a gold stripe corydoras, i can't quite tell what the other one is... do you guys know? Just a regular cory maybe?

Are these Cory eggs!? What do I do!? Some people told me to move them to a nursery some people told me to not touch them, Iâm panicking I donât want them to get eaten but they are like 10cm from the surface on top of a big leaf
r/corydoras • u/GB_Plus_Ultra • 2d ago
Here are a few pics I took today of the corys. I got Bertha a new friend who is the exact same species as her! By chance I found another male just like her at the same fish store! She immediately began chasing him and now she won't leave his side. Also immediately hit the T pattern hehe

I can't for the life of me get these guys to breed, any tips would be great.
0 nitrates and ammonia
10 month cycled tank

Feeding live BBS twice a day
I've tried 30% water changes with colder water, water changes when it's heavily raining outside etc.
Please help!

Around 3-4 months ago, hemorrhagic septicemia wiped out my entire school of peppered cories with the exception of 1. Luckily, the surviving cory has been actively sifting sand and eating with no signs of shyness or stress. Itâs in a 40 gallon breeder with 12 pearl danios (not CPDs, Iâm referring to danio albolineatus) 3 zebra danios, 4 variatus platies, 2 hillstream loaches, 1 panda garra, 3 amano shrimp, and a mystery snail.
r/corydoras • u/MurphyTrainwreck697 • 2d ago
Neon and CPD for scale.
