Corys And Infections

[techen]

Am going to say are corys not that much of a hardy fish?
 
I just saw one of my corys with large fluffy dots on them, That's another cory with the same infection in the space of a month. Are they prone to this?

From experience, Cory's can pick up diseases more commonly because they primarily sit still in one place making it easier for parasites to attach to them. On the other hand, when scared they can jolt quick, sometimes into sharp objects or other fish which results in skin damage/irritation which in turn can caused fungal/bacterial infections.
 
So I guess the answer to your question is no; they are just as hardy as other fish but they are often in the wrong place at the wrong time.
 
 
Where are the fluffy dots on your fish?

On the side of his body, It's only one cory that has it. But the cory before had what looked like an anchor worm and died from it.

Do you think you still have an anchor worm problem in that tank? It could be that the anchor worm has separated from the Cory that you mentioned in your original post which has left a small wound which has allowed fungi to form and grow.
 
From experience, the optimum treatment for this is to:
 
- Carefully remove the fluff
- Topically apply malachite green to the spot where it was removed
- Take the fish out of the water and seal the wound(s). You can seal the wound with: http/www.ntlabs.co.uk/products/Wound-Seal.html .
 
While the fish is out of the water you should continually pass the tank water over it's gills for oxygenation up until the point you quickly apply the malachite green and wound seal.
 
Never use any of the products near the operculum or gill itself.

Well, I was due to remove my corys as am going to get hairgrass and bottom fish are not recommend. Am just abit depressed that another cory has to suffer, it was going fine for a good month.

I'm really sorry you feel that way. At least you know how to treat the problem or how to advice the new owner of the Corydoras' of how to treat the issue.
