20 Gallon Tank Cory dying slowly but known reason

Caterpie

Hi,

Can someone help me? I posted another thread explaining about my sick cory, but I haven’t found help yet.

he was very lethargic, very white looking and it was very hard for him to maneuver his turns. I fed him and he tried to eat first, but then he didn’t move anymore. I could easily pick him out with my hands and I put him in a cup (I don’t have a hospital aquarium :( ) now he looks like dead inside the cup, even laying down, but he’s still breathing.
I put 1 drop of PraziPro in his cup just to see if it could either help or just bring his destiny faster. I have not hint of what could have made him sick. Everybody else looks happy and healthy.

3 days ago I fumigated my apt and I sealed the aquarium for 5 hours. It wasn’t fog fumigation, it was water spray. Everybody seemed fine after I opened the tank.

I did a 50% water change last night and now I added 1 bag of carbon in the filter. I’m just trying stop whatever made my fish sick.
The fish is dying slowly I think, and I don’t think it’s good idea to put him back in the tank with the others.

I tested the water parameters and it was 0 ammonia, pH 7.6, nitrite 0 and nitrate 20. I haven’t measure again after the water change.

I feed them flakes and bottom feeders food.

Help please!

I'd help it out of its missery.
Is that a hole in its belly ?

How long have you had this little guy/girl? I can't see anything obviously wrong. As sad as it is sometimes we lose fish for what seems like no reason at all.

When I first set my tank back up after being out of the hobby for a few years. I added 3 bronze, 3 albino and 5 false julii corys. Over the next couple of months I lost 3 of the false julii. After about 4 years I lost my female albino. Just last month I lost one of my 2 male albino's.

All of this to let you know. Sometimes we lose fish for seemingly no reason whatsoever. One day they seem healthy and the next day they are gone. Normally when one reaches this point there is very little we can do to save them.

He was with me for only 5 months. I bury him already :( thank you for sharing your experience, this is my first fish tank and it’s pretty painful :( I hope this won’t happen again soon ;(

It was just his guts or organs I guess, because they’re very transparent and on the picture it looks like a hole. :(

I am sorry you had to deal with this. It is never easy losing a pet. Even a water pet. This unfortunately is the down side to this wonderful hobby. It is going to happen no matter how well we take care of these little guys. I too hope this doesn't happen again soon.

As a group Corys normally live a long life but as you have just experienced, some we lose early in life. Right now I have well over 25 of the little vacuum cleaners in my tank. I do love these little guys.

If you have both male and female in your tank one day they will start laying fertile eggs. Cory eggs are really easy to hatch. You will have to collect the eggs should you want to try to hatch them though. All the fish in the tank including the corys will eat the eggs. Now that the weather has cooled off here my corys are back to laying eggs daily. Lots of free food for everyone.
