Hi,

I've got this cory that I can't get a positive ID on. Here's a picture of it. It's about 5 cm in size now and I have 4 of them.



Any advice on it's ID is greatly appreciated. Thanks!

Cheers,

benny

You have young Corydoras delphax They reach around 65 mm (body length)

benny,
those are nice-looking little catfish. they really caught my eye! i am going to research them to see if they might be nice tankmates for my Hoovie. i have been looking for some smaller catfish with Hoovie's same color-scheme, and which would be compatible with him and his tank set-up. good luck with your fish!

Great find! I'm geting 4 (Hens teeth) Julli's tomorrow.

Hi Ian,

Thanks for helping me identify this fish. Initially, some of us thought it was C. melanistius brevirostris.

Hi Gail,

At 5 cm, I thought these were adults already. Didn't realise they are fairly young. Pretty shy creatures compared to C. similis, but great fun to watch them burrowing in riversand if they do come out. Hope you find them as suitable tankmates for your Hoovie.

Thanks!!

Cheers,

benny

Just a couple of bits of info: -

There are no longer any Corydoras sub species, which means C. melanistius melanistius and C. melanistius brevirostris become C. melanistius and C. brevirostris.

Hi guys,

My delphax seems to be fading. Compared to the first picture that I've posted, it really seems pale.

Here's a picture for comparison.



Anything to worry about?

The abdominal region looks a little strange. May be suffering from intestinal parasites.

Glad this got bumped up--now I know what kind of cories I have! The LFS gave them another name (can't remember now what) but I was surprised at how much they've grown. Now I can look up more specifics on them.

Your C. delfax have aclimatised to irs surrounding. If you put them over dark sand or gravelthey will darken.

hi Silurus,

Care to share how to look at the abdominal for intestinal parasites?

One point that I forgot to add is that only 1 out of 4 dephlax is losing its color. The rest are fine. Does that mean that the rest is not acclimatised?

Cheers,

From what I can see from the photo the fish appears to have a well-rounded belly, but the region immediately behind that (between the pelvic and the anal fins) is somewhat shrunken in. A well-fed fish usually has a both regions rounded.
It may be the angle of the camera when the pic was taken, but that's what it looks like to me.

I see.... thanks... we seem to be having some problems with our cories these few days... there were quite a few number of casualties... we're still wondering if it's the water, food or the hot weather...
