with a black background and white sand mine looked like ryans. now i have it in a clean bottom tank with a midnight blue background and it is very dark. you can see pics of it in my update thread in the gar media lounge.
Your Cuban might just be dark from stress as result of being moved, being kept with some of those fishes, and/or water quality. I noticed with my old one that it would darken if it was stressed due to tankmate or water quality issues, and it would return to its normal coloration once the issues were corrected.
water is the same as in the other tank it was in before. the ph has always been low. i can never seem to get it right. my ph in the 40breeder with the aragonite sand is the same as the ph in the 180gal. i am going to get the black/white african cichlid sand. i'll see if that will change its color.
it has been in the 180gal for a while now. everything seems to leave it alone, but it does get crazy at feeding time. it eats and acts just as it allways have so i am not sure if it isn't due to lighting and that it likes to sit under the overflow of my hob emperor filters.
Shiny Bronze? Nice i tot if with black he might turn darker.
Anyways whats ur substrate colour? or if bare tank, its also black?
