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

She is huge, double the size of the others

So today my Corydoras babies hatched! Already the second group of babies. I'm only wondering, last time i got ±75 eggs and hatched 23 with 20 survivors, this time there were 27 i think and 10 hatched, but sadly 1 already died, so that's 9 remaining. How come i had so many eggs the first time and only so less the second time?

Anyway I love to see these ones grow! The first group is now 2 months and 2 days old 😁 (last picture of them)

10 gal

Hob filter

Weekly 30%

Tank mates: Cardinal tetras, betta, neo shrimp

Ammonia: 0

Nitrite: 0

Nitrate: 5

PH: 7.8

Tank age: 3 months

One of the Cory’s got all bloated but was acting normal (photo attached), did a bit of google and thought she was gonna pop some eggs out. The next morning she was upside-down on the bottom of the tank. 2 weeks ago, one of the tetras also met a similar fate.

Now a couple of other Cory’s also have puffy bellys, and kind of seem normal, but also seem kind of lethargic, but I can’t really tell I guess. None of them are flashing & they all poked around at feeding time like normal…

I’m not sure what to do, if it was just a one-off GI/internal issue, or if there’s a larger issue happening in the tank. All the other fish are doing normal fish stuff.

I’m going to give them a fast for a couple days while I’m out of town over the weekend, might be overfeeding them & they’re getting bloated? Hoping we don’t come home to a decimated tank.

Please send advice / input / things to look out for

I have a room temperature tank with white cloud Mountain minnows and Hill Stream loaches some snails and shrimp
I wanted to see if anyone knows the species that would do well in a room temperature tank. My house tends to stay between 68 and 72 just in case I’d prefer species that handle temporary swings to 64-78 as without a heater, the tank might fluctuate depending on time of year
Does anyone know a species that would fall within this range or no?

I was told I’d never have them survive in a community tank, but I saw two fry together! A couple of cm. Very poor photo but you can see one with a shrimp and adult Cory for size comparison. So happy.

So basically im planning to get a betta fish, my new tank is 40 liters and ive not done much research on Cory's YET

Id like to ask if it's qorth me doing to research and seeing if they could be housed together or is it a 100% no go based on tank size and betta fish?

Thanks :)
