Lazy Cories!

Have you tried giving them some defrosted bloodworms? Corys usually cant resist them. Also garlic can stimulate fish to feed so if you could put some crushed garlic in the tank at the same time as defrosted bloodworms then you might be able to coax the skinny corys to eat.
 
Tried the bloodworms this morning. They didn't so much as lift a whisker :( Not looking good at the moment
 





:-(
It's still alive is the saddest part. Anything left to do? Should I euthanize?
Are these parasites going to get into my other cories or even other fish or is it more likely to do with diet as Baccus suggested?
 
Is it possible for fish to decompose before they die? There is a slight ammonia reading which wasn't there3-4 days ago.
 
Catfish to release ammonia from their gills, perhaps with what ever else is going on internally the catfish is releasing more toxins as its body appears to be eating itself.
So sad to see a cory in that situation, and I think the best course of action is to euthanize

, at least then you know it is beyond suffering.
If your other corys are all active and well, then I really don't think this wasting problem will occur in them, I really feel is it related to a point in the corys life where they where starved (purged is the term they usually use in relation to transporting live fish etc) and the gut flora never recovered. Because we don't know how the fish where prior to leaving the breeder, we have no way of knowing if the starving could of happened there when in large numbers the growing cory(s) had limited access to food, then starved/ purged for transport and then potentially not received enough food in the pet shop.
As Eaglesaquarium said other people have experienced similar issues with Pleco's and I seem to recall reading somewhere that the young pleco's need to gain their gut flora from their parents droppings. The organisms they need in their stomachs to break down the woods and things they chew on they are not born with.
 
I wish I could easily send you some of my excess peppered corys, but I have had bad experiences posting fish in the past and coming into winter is not a good time to post without heat packs.
 
What are you feeding them Talltree. This Paleatus indeed is very thin. To me this could have some causes : Most common one is that these mainly carnivores are on a wrong diet of algaewafers / vegs ans get to low protein. Healtproblems / death can be the results. Other possible causes : a bacterial infection or parasites (worms). In the first case they'll show red blotches aso.
 
Especially C.Paleatus are hardy fish, that should show "Chubby" and can live for 20 - 25 years. They are cool-water Corys.

Mine Paleatus are always waiting for the glass to be fed. I feed them frozen bloodworms, artemia, crumble the tablets so they have to "hunt" for it. Keeps them busy (hoovering the tank) most of the evening.
Sometimes I feed them some very (protein/fry) powder. They are a day searching for the tiny bits of that !!

It's a real shame to be sure. Specially with such adorable fish as small plecs and cories. :(

I feed mine wardley shrimp pellets intended for corydoras. Not much vege matter at all in it I think. I've fed other cories it with no problems. :/
I also occasionally feed frozen bloodworms and skip feeds frequently.




I will euthanize late tonight/ tomorrow morning. May they rest in peace. :-(
 
Ahhh okay. Why do you skip feeds frequently?  Strange thing is its color is perfect. Can you place a pic of the others ?
 
I've never fed fish heaps ya know? I prefer to give them larger feeds less frequently than small ones frequently. I'm not sure why I do this exactly. Seems for natural to me I Spose. :dunno:

I'll put up a picture if a healthy cories tomorrow :)
 
Very sorry for your losses.  It is frustrating seeing a problem and not being able to do a thing to help the pet.
 
Its probably your Nitrates, when they get higher then 20, Corys will sit at the bottom to avoid the slight burn through their gills of a higher Nitrate level. Gravel Vacing will reduce your Nitrates. 0,0,5/10 is usually where you want to keep it. My Cories lay around quite a bit too, but as soon as lights are out or food is introduced they're going crazy, if this isn't happening, Your levels are likely not comfortable for them. 
 
If it is parasites though, I have had experience with my cories and my pleco getting internal parasites/bacteria. I actually did a lot of research and asking around at my LFS about what type of medicine I should use, or medicating the food, and I Actually found that adding about 1 Tsp/10g of Aquarium Salt and bumping the temp. to about 82 Degrees F for about a week, killed the internal parasites and my Pleco (who I thought was DOOMED) and my Cories All survived! I've found most ppl prefer the Salt/Temp method over Medicine. 
 
Began Euthanizing as soon as they show signs of the sickness. It is kinder that way. Down to 2 now. :-(
Just had to euthanize my favorite specimen. A large female. So beautiful.
