fishy-fish Posted January 28, 2012 Report Share Posted January 28, 2012 I just noticed this today. One of my GBA's has a dark brownish/black spot on its back. None of the others have any such markings and I think its new as I haven't noticed it before. Is this a disease or maybe burn mark? They do like to clean the algae of the heater so I'm wondering if this one got burnt. Any ideas? Here's a pic Quote Link to comment Share on other sites More sharing options...
Zayne Posted January 28, 2012 Report Share Posted January 28, 2012 i would say the parents have a hint of brown bristlenose in them Quote Link to comment Share on other sites More sharing options...
alanmin4304 Posted January 28, 2012 Report Share Posted January 28, 2012 I would say that it is leucistic, which is a genetic characteristic that prevents the proper depositing of pigment. It can be complete or partial so can cause light patches, complete light colouring, light colouring with normal patches or a general lightening of colouring.

GrahamC Posted January 28, 2012 Report Share Posted January 28, 2012 Other's have recently posted pictures of their GBAs with "black" eyes .... so a similar variation. Quote Link to comment Share on other sites More sharing options...

Adrienne Posted January 28, 2012 Report Share Posted January 28, 2012 How long have you had it for, how old is it an how many of them do you have? You may have not seen this particular GBA for some time and therefore have not noticed the mark. It does look like the mark often seen on GBA these days. I suppose in theory, it could be a bruise but I think not. Just keep an eye on it. If it grows rapidly or the GBA seems off colour then it is more likely to be something other than a natural sort of birth mark. Quote Link to comment Share on other sites More sharing options...

I observe them on a regular basis and this seems to be new. I could be wrong, but I know there was no markings at the time of purchase. So it's definitely something that has developed over time/age.
