What do baby Pygmy cories eat?

So I recently found 3 teeny tiny pygmy cories swimming around on the surface and substrate (they literally look like tadpoles that are the size of half an eyelash). Their mouths must be so tiny and I have no idea what to feed them 😭 what do I feed them? I’ve been giving shrimplet powdered food but I don’t know if that’s what they eat.

Little guy has not shown much growth compared to his siblings (shown with)

Wondering if it’s a genetic thing or other? He gets lots of food! Been monitoring him and he’s always been very active and healthy showing no signs of ill health.

I love giving them daphnia!!!

I just started a daphnia culture (and therefore a green water culture) and it’s only been a couple weeks but I love it !!! The peas are such piggies. You give em anything and they gobble it right up. At least with the daphnia they’re tiny so the puffers spend a lot of time chasing em down to get a meal. Hoping the cories figure it out too!

My other tank has a lot of nano fish and tetras and they looooove em too.

cory… sleeping? :(

I just added a school of albino corys to my tank… they were all super active after acclimation and addition but this guy is settled down and worrying me a bit. First time owning corys, what can i do/is this normal?

2 Pygmy Corys for now

Hi all!
Currently I only have 2 Pygmy Corydoras because that was literally all my lfs had left. They’re actually surprisingly active together right now, swimming around the tank and staying near each other, not hiding or looking stressed.

The problem is I can’t find more locally at the moment, I looked around 8 shop and non of them had any. Due to the holiday I won’t be able to get more for around 2 weeks ,because thats when the shipments from abroad will happen, unless I order online from another city.

Do you think 2 weeks with only 2 pygmies is okay if they seem active and comfortable? Or should I urgently try to source more sooner somehow?

Tankmates are:
- 9x Gertrude’s Rainbowfish
- 6x CPDs
- 1M 2F Rhinogobius gobies
- 1M 1F Clown Killifish
- 2 Hatchetfish (Same situation)
- Shrimp/snails/mussels

Tank is planted alongside wood, dragon stone caves and lots of cover/current breaks.

Help please, has he an infection?

I just saw he has some white stuff on his nose. NH4, nitrites are at 0 and nitrate around 10. Should I try to quarantine him?

Corydoras "bullying?" Mystery snails

Today I was watching my aquarium snail and saw how one of the corydoras began eating near or something on the snail which made the snail retract into themselves.. why do they do that?

ive noticed that my snails have gotten less active.

Tank filters?

Hello everyone! I know this might come down to personal preference but I thought I would ask anyway. I have a 10 gallon planted tank for my panda corys. It came with a filter that at first worked really well but is already just not running. In their reviews for the tank kit, this is a common problem. I knew it when I ordered the tank but only about 25% of reviews said that so I think it’s possibly hit or miss. Anyways, clearly I got one that doesn’t work that well for whatever reason. I want to buy a filter that actually works well for these tanks. I do not intend on putting any other fish in this tank. Maybe a snail or two but that’s it. I don’t really care what it costs, as long as it works lol. Thanks in advance!

...suddenly, MANY cories

I started with a group of 10 G. hastatus in August and only lost one during the initial acclimation to the tank/post-transit stress period. Tragedy struck around Christmas and I lost fish very rapidly during a two week period, leaving me with only 5 survivors. Not much in the way of visible symptoms, so I treated for columnaris. I also slowly started softening my water by diluting my tap water with distilled, and began adding botanicals to the water.

I started to see small fry here and there, but very rarely would I see bigger fry, so I wasn't sure how many were making it to adulthood. Then, I got busy for about a month at work and while I kept up with tank maintenance, these guys are so shy you really have to sit with the tank for a while before the adults will come out. There are also plenty of hiding spots...so I had no idea that they were slowly forming a horde in there.

...I think they like the way the tank is now, what do you think? (They...they do stop breeding before every surface is covered in babies, yes?)

What species are these?

So, we've bought those cories home a few weeks ago and im fairly certain I know what species they are but I want to be 100% sure considering the price we've paid for them

1st few days

I picked up 6 (false) Julii corydoras on Saturday and man they’re oddball behavior has been a rollercoaster. Basically every weird thing I’ve noticed I can find a thread on here that says “yep, they’re little weirdos and that’s normal”. I love them, but wow, I’m hoping I can settle down and stop thinking they’re having problems when they’re just being their little weirdos selves- literally what drew me to them in the first place!

This video is from the first morning after I got them when I was certain something was wrong but of course, they were just resting and hiding, after feeding them I was then looking up “is zooming around after eating normal?!” 😂😩
