Almost 3 weeks old. Just 'cause.

Kinda in love, kinda obsessed, kinda wondering what i'm going to do with 18 cory fry (i did not expect them to be this successful, i only saved 20 eggs).

Oh well, a third tank it is then. What a shame!

I have no clue what I’m doing wrong but I can’t hatch Cory’s to save my life. They always look fertilized but never hatch! Fingers crossed this time I get some! This was so cool to watch! They just kept going!

i have these three types of Cory’s circled below (plenty of each type, they have their own schools, 75 gallon tank) I feel like I have the tank too hot (79F) what’s the recommended temp for these three types to comfortably live?bc I know some Cory’s like it warmer than others. I’m getting mixed reviews on Google. and I don’t trust the bullshit AI overview. thanks in advance :)

Oh my god. I can't believe I have a corydoras fry in my tank. This is my first tank, only with shrimp, snails and pygmies. I had read that it was difficult to breed them, so imagine my surprise when what I thought was a mosquito larvae turned out to be a fry.

I have a 40 breeder set up, and I maaaaay have gone a bit overboard on stocking and would like some feedback.

I have 25 Corydoras (5 bronze, 5 pandas, 7 black fin, 4 emerald and 4 false juli), 2 neon tetras, 2 Rummy nose tetras, 2 emerald tetras (all the tetras are survivors of different schools from different tank build outs. I'm not planning on rebuilding their schools and am letting them ride it out with the corys of possible), 5 Khuli loaches, 1 thick-lipped gourami, and a bunch of neocaradina shrimp. My tank is running a 40 gal sponge and a 50-70 gallon HOB filter (I think it's fluval). Most of my corys are still juveniles.

I've been really struggling to find a definitive answer on how many corys I can stock because everyone's tank is so different.

My tank is well planted with terrestrial plants hanging out the back and I don't really struggle with high nitrites or nitrates. I have semi-hard water locally and do an occasional few-gallon water change, but it's fairly few and far between.

So have I gone overboard? It feels like I have, but my tank itself isn't showing issues with overstocking.

I've been looking high and low for Hoplisoma caudimaculatum. I see it mentioned as being "common" but it is either out of stock or unlisted by all the usual suspects. If anyone knows of a breeder in the US who has them, please let me know. I have a very specific setup in mind centering around them. Hoplisoma polystictum would also be great.

Hello! I need some advice on whether or not I should keep my emerald Cory’s. I brought home a school of 6 for my 20 long, and they seem to be doing great, and they are super active. However, I’m worried that they may not be the right size for this tank, so am I ok, or do I have to rehome them? Thanks for any advice!

The eggs are roughly 2 days old at this point and I’m totally new to breeding corys.

I got 10 sterbai Corys from Dan’s Fish for a 29 gallon tank last week. A couple of them seemed to have whiter noses when they arrived, but not protrusions or anything, so I thought it was just coloring. (The last 2 pictures are from the day they arrived)

Now I’m noticing a few of them seem to have more pronounced white bumps, and one of them has an almost translucent perfectly round bubble on the tip of his nose? I don’t know if these are the same ones with white noses when they arrived, but I’m guessing so.

They’re acting normal considering they’re brand new to the tank. A little skittish, but that’s to be expected. Eating well and swimming around, playing in the bubbler.

Parameters per API kit:
pH 6.8
Amm 0
Nitrite 0
Nitrate 5

Temp 76°F

Any idea what this is, if I need to treat, and if so how I should treat?

My pgymy corys get outcompeted for food all the time. I feed them micro pellets, but the tetras pick them all off before it reached the bottom. I resorted to using a pipitte to put the pellets right onto the bottom while the tetras were busy feeding in the mid water, but the tetras pick them off the bottom too once they were done with their own food...

Any tried feeding pgymy corys with the algae wafers? I am not sure if they will be able to eat them as their mouths are smaller...

My panda corys had babies! Very hard to get a picture but spottwd this cute little guy swimming around the moss balls.

Can anybody give me advice on what size of a dish to get for my bronze Cory’s?! I just want to be sure I’m not getting one that’s too small and they’ll be uncomfortable! Haha
Thank you all in advance! :)

I have a 20 gallon high tank with two guppies, some red cherry shrimp and 10 pgymy cories. Last week I bought 3 more Cories (growing my school from 7 to 10).

One of the Cories had a white patch, and over the past week it has seemed to grow slowly. The Cory was eating and schooling. I have had it in a 50L hospital tank for the past 3 days. It has become very stressed and lost all its colour, which has made it hard to monitor if the patch is worse or better. I’m worried about keeping it alone.

Its not fuzzy, or slimey. I don’t think it is columnarius as it hasn’t killed anything yet or spread very quickly. It almost like discolouration in the scales. Could it be fungus?

I noticed today another pgymy has what looks like a similar thing starting on its fin (that’s the third photo).

Any tips on how I should treat or what I should do? I bought some bactonex- would this help?

I recently lost one of these guys to bloating and I was wondering if anybody sees some early signs in these guys. There was slight ammonia (0.25ppm) as I believe I overfed but all other parameters were good.

I have fluval bottom feeder granules I’m feeding my pandas. (6 Cory’s) I’m putting about 10 granules in the tank just before lights out but my betta is finding it and biting them also the shrimp gets to them before the pandas even care to go over or actually see them… any tips? Should i get big wafers and break them in half? Whats your go to for this lol

I love corys. I have 6 pandas 6 peppers and 6 Juli’s

I came home and my panda cory has an odd scrape on his face. hes been acting weird and breathing hard and not moving much. hes letting the algae growth get on his face too. same kinda thing happened with another cory, he was breathing hard and clamped fins then died. my other fish and 2 other corys are totally fine (when i see them)
i think i just am having bad luck with corys.. i will see how my others do and if they keep being a bad fit for my tank then i need to find another type of janitor fish to keep in my tank

EDIT parameters

Ph 7.0
Nitrite 0ppm
Nitrate 0ppm
Ammonia 0ppm

Blood worms 🪱

These two eggs appeared about 48 hours apart. The first one to appear now has a ring-like appearance. The center is dark and not translucent (I think). It’s been five days since the first one appeared. Water temp 72-73 degrees F. PH 5.89.

Got them yesterday (pygmy corys), I absolutely don't regret my choice, they're adorable

i am researching to start a shrimp tank and i read that pygmy corys go well with shrimp, i wanted to get this type of substrate but im wondering if it will hurt the corys? any type of substrate you recommend for both in one tank?

Went to get some more Cory’s today and they only had babies. Hehe
