These past two days, my senegalus seems to have lost his appetite. There is also some noticeable darkening on the edges of his anal and caudal fins. Dorsal finlets do not seem worn, but the spines appear slightly darker as well. Are these the symptoms of a disease? It didn't look like fin rot to me since the only rot I've seen was white.
 
not red just darkening right?
How big is it?
is it still eating and swimming about?
 
check the water
did you change the gravel color that would darken your bichir but wouldn't make it stop eating
 
The gravel has not been changed recently, so it is not an illusion that makes the bichir appear darker.

He still eats, but not as willingly as he used to. As far as I can tell, there is no red, it's just darker. Was less active when I first posted, but his activity level has risen since then.
 
As long as it's still eating, I wouldn't be too worried. Some species (mainly lower jaws, but possibly upper jaw as well) will go through fasting periods where they eat little to nothing, for however long they choose to do so.

The contrast of my polys color goes through cycles, especially the laps and endli's, which you may see referred to as 'unstable' pattern (mainly hear that term when talking about Datnoids).

However, it never hurts to keep an extra close eye when observing a change in behavior/coloration, if only for the sake of being on top of things.

I'm not aware of any causality between disease and darkening pigment.

I wish you and your fish the best Druu.

Ah I see, now I'm aware of one :ROFL:

What ways can a fish happen upon such a disease or pinching of the nerves?

Is it genetic or could they also be caused by some other means?
 
tumor is the most common and sometimes can be cured by the addition of iodine to the water colum-Anne
 
Thanks for the input. He's eating only one pellet per day as opposed to 5 or 6 per day. I will keep an eye on him and report any changes.
