I'm on several forums and over the years (2013-now) I've read several threads about C.sterbai having a greyish layer / spots on their body. Some mild, some extreme. Does anyone know what is causing this and why it seems only to be on C.sterbai? Can't wrap my mind around it.

Thanks in advance.

Strangely I have never kept the species asked an update for.

What exact type of sand is it?
One of the corys seem or have greyish spots on the head as well.
Is there a good waterflow ?

All my Aeneus are in unheated tanks.

My guess would be Corydoras Brevirostris.
To my knowledge Punctatus isn't seen in the trade for years (Living in a no-catching locality in Surinam).
Lots of "spotted" Corys are sols labeled Punctatus (latin for spotted) though.

just in the filterflow this morning !!!

I agree with @corycory.
Feed my Corys every day and keep them in shoals if their own species. You'll be amazed about social behaviour in that case.

Not being offensive, but why did you fish of which you knew had Ich? To my knowledge Corys are sensitive to salt and some to high temps as well. I'd go the med-way and treat as mentioned in the manual (often half dosing). If there still aren't any spots I'd wait to be sure it has got Ich. In the ...

Mine neverrr eats algaewafer or vegs.. It only goes for protein (coryfood), frozen bloodworms, brineshrimp.
To me they defo are less vegetarian than they are thought to be.

Costia?

Seriously??? Having three of those myself, but defo not with a pattern like this one.

Can one of the experts overhere ID this juvenile catfish that a friend of my got recently? Thanks in advance. Regards Aad

The floating often is caused by new Corys (in stress) will take a bigger gulp of air than normally (secundary breathing-system). To my knowledge Trilineatus are found over a widespread aerea and will therefor often be different in shape, color, markjngs aso. The one in front of the tank seems to ...

PFS has a very natural color looks a bit yellow, but I've 4000K tubes causing that !

Thanks again !! A pic of my Peppered Cory Nice cory. Does that cory have black or red eyes? Also, is that cory yellow or white bodied in real life? Lighting can make white fish look yellow. Speaking of body color, I know that my albino BN plecos can change body color depending on: 1) Diet - foods ...

Andy, to my knowledge two albinos (recessive gen) never can have brown fry. That is incorrect. A red eyed white albino male and a red eyed white albino female may in fact produce 100% normal brown fry, if the two albinos are from different "clans", with each clan carrying an albino gene in a ...

Hi, well, I am not a biologist, so perhaps a geneticist can better explain (or perhaps even explain why my explanation is wrong). And after looking it up again, I realize that the english word is actually xanthism.. Those are different kinds of mutations: leucistic individuals do not have ...

Thanks Sandor. Only think it isn't the light that causes black or blue eyes. My 2 females do have blue eyes, but I've seen "normal" black eyes elsewhere. Thanks for explaining the "Rio Paraquay" - story. You're the first to me that uses the word Xanthoristic in english (I've a yellow peppered Cory ...

most likely. But the parents of these fish were also both red eye albinos and threw brown fry as they got older. It remains to be seen whether the process will repeat in this generation. Aad- both parents were red eyed albinos. and they definitely threw brown fry as they were alone in a 10 gallon ...

I had a pair of LF albino's that threw nothing but albino LF fry for a long time. Then one day they started to throw shortfin albino and then both shortfin and long fin brown fry. There is more to it than simple Mendelian genetics. Age or environment may also contribute to the pigmentation/lack of ...

Besides of that there seem to be two ore more strains of albinos. A "yellowish" one with red eyes and a more whitish / pink strain with red eyes. The first is often sold and mislabeled as L144

Doesn't have the false L144 black eyes instead of blue eyes for the real one ? The false L144, aka Ancistrus sp. (4), differes from the Albino variant with the lack of the red eye typically associated with albinism, as well as a lack of pattern coloration on the fins as well as the body that is ...

Doesn't have the false L144 black eyes instead of blue eyes for the real one ?

Could it be a lack of protein is a possible cause. Noticed my Oto's aren't that great algae-eaters, but love protein.

Beauties !!!

It's a leucistic Ancistrus cf Cirrhosus to me. Not a L144, which have blue eyes.

Laetacara Curviceps or Dorsigera ?

Well its a shame but I guess it never said rounded edges so they never lied. I've been using this for past 2-3 years "http://www.zooplus.co.uk/shop/fish/decoration/aquarium_gravel/gem_stone_gravel/285153" 2-4mm grains and rounded but its not done anything harm as far as I can tell but its not great ...
