Re: URGENT: Please help, sick skunk cory

Certainly a water problem, I am certain it is nothing parasitic, but bacteria will infect damaged areas. The first thing I would do is make a large water change 75% and then add a full dose of API Melafix. The red blotching under the scutes is hemorrhaging most likely caused by nitrite burn. Quite o...

Re: Poorly cories

Looking at the tank statistics I think the main problem is that the water is very soft and your nitrates are up a little, and it is the presence of nitrates that is probably causing the problem. The first thing I would do is a 50% water change and then reduce the amount of food. With very soft water...

Re: Corydora ID

I think for you to get a the true colors of the fish to show you need to keep them over a natural tan colored substrate. Black substrate will always make your fish go dark.

Re: Corydoras Zygatus?

In my opinion the fish in the picture are albino C. zygatus, most if not all albino fish will show the type colour pattern as in the effect of brushed velvet.
I can clearly see all the pattern characters of C. zygatus in these fish.

Re: Is Corydoras sp. CW023 = CW014?

They are both the same species, CW014 was determined on specimens that had been kept over black substrate, which darkened the fish giving them a red stripe. Over normal lighter substrate the stripe is orange. These are not the same and should not be confused with CW010 the 'Gold laser'

Not C. schwartzi. this species has a black blotch at the base of the first two or three dorsal rays, this colour extends up into the first two soft rays. the dorsal spine is grey. Your fish looks closer to C133 although it does not look in the best of health.
