Sich Schwartzi Cory

[chokko]

No comments to my simiar posting in Corydora sub-forum (so feel free to delete that thread)

He/she seems happy enough. Is just as active, and eats as much, as the other corys.

Has a smooth white wart like bump on belly.

Smooth white growth on both anal fins. The anal fins don't appear to be spread out fully, but are not clamped against fish body.

Ideas?

Front-on. Can see 'wart' below the vertical barbel, and bulges on the (out of focus) anal fins.

'Wart' and slight white bulge on lower side of his right anal fin

Im sorry im not sure what those bumps are but i like your cory! hope s/he is ok...sorry i couldnt help

 

[chokko]

it's ok, i was about to indirectly bump the thread anyway, with this piccie:

Murse Chokko has admitted a second patient with suspected symptoms. Waiting for doctor to arrive in the thread

 

[MrsM]

i had a google...could be skin flukes...still not sure though, maybe google cory with skin flukes...

Great pictures

. The lumps look like cysts of some sort.
Did the cory come with the lumps or did they only develop after you had it for a while? Just trying to rule out something like anchor worm that somebody has pulled off and left the head behind.

If it was only one lump on the belly area I would have thought a hernia of some sort, but since these lumps are in other places I am thinking its either a parasite that is still with the fish or the results of treatment from a paracite attack.
Sorry I can't be more help.
At least its eating well and seems in fine spirits, so half of your battle is won.

I didnt look at the super close when i bought the schwartzis...but doubt those lumps were there - wasnt hard to spot them.

maybe it picked up something in communal tank at the fish shop whilst waiting for me to pick them up. (i've had them 2 weeks now)

have shown them to the only knowledgable fish shop in canberra, and they didnt know what it could be.

maybe i will try a salt dip later today, if parasites seem the likely cause.

 

[Baccus]

I really wish I could be more help, did you get them from the same shop that you showed them too?
It might help on diagnosis to find out where they came from, eg locally bred, recently imported from say Asia where many south American fish are commercially bred. I doubt wild caught would be allowed into Australia without very long expensive quarrentine times.

 

[chokko]

no i ordered them from a more general pet store (that sells rabbits and stuff too)...and the manager there believes nitrites are no problem for freshwater fish..so not the most cluey bunch around.

the Schwartzis came from Aquarium Industries (melbourne?). Don't think their stock sheets state if they are wild caught or locally bred

 

[Baccus]

Really unhelpful of them.

Because we can only see external lumps with no obvious opening/ exit area parasite wise I am inclined to think an internal pathogen/ parasite which a salt dip wont really touch. I will do some hunting on what interal parasite killers are available in Australia and try to work out what will be safe for use on corys while also hitting the widest range of fish pests.

Maybe they are just skin agitation from something in the previous tank or in yours.
A salt dip might not be a bad idea, only slow salinity though as Corys are not too salt friendly.

Then again, if they arent getting worse, maybe just monitor them for now?

I prefer to buy locally bred fish when possible, that way they are more acclimatised to my water conditions.

To be honest though, I'm inclined to think they are just errr, slight defects.
Some diseases can deform fish... you need to just monitor I guess.

this salt bath was proudly sponsored by Cadburys chocolates

Little troopers just sat there until exactly the 5 minute mark...then started darting everywhere

 

[Baccus]

And to think I thought Cadburys only did choccies

.

Let us know if there is any improvement in them after the dip or if anything else now shows up.

 

[chokko]

gave another salt bath tonight...still definately something on its left anal fin.

Big picture warning again, for you 56k modemers

That is really odd, it is almost like it has been spawning and a deformed egg has got stuck. But looking closer at the pictures it seems more like a growth/ deformity. Because it is a white mass it looks like a begnin cyst. Almost like there has been an infection/ paracite there previously and the body has formed scare tissue around the area. In one of the pictures it actually looks as though the other anal fin also has a slight lump/ clubing of the fin.
How many salt baths where you planning on carrying out?

I have a couple of diseases that you might want to investigate and hopefully rule out as afflicitng your cory. Unfortunately if it is suffering from them the prognosis is not great

Lymphocystis

Glugea

Hennaguya

 

[chokko]

Thanks for that info.

Found some goods pix of the Lymphocystis on a corydora on another forum. That could be it.

Won't do anymore salt dips now i guess...just wait and see what happens. Don't want to stress them out more than need be.
