when I go to other websites ... the reasons I am seeing for loss of color are fish TB and neon disease. I have just lost a guppy with a bloated stomach (which I though was dropsy since I saw pineconeing and he lost some color before his stomach became bloated).

My biggest cory catfish is now paler when compared to the other 3 false Julii and her dorsal fin is not standing up.

Water conditions are good (Ammonia/Nitrate 0, ph 6.8, Nitrate 5 -- weekly water changes with water conditioner 50%)

Any thoughts?

My remaining 2 guppies seem OK -- my blue guy still pesters the remaining one so he hides all the time now.

Do I seperate and start up my hospital tank? I hate to pull out 1 lone cory.
 
loss of color is a sign of stress..but does not mean the fish has TB.

was the guppy a male or female? is is possible it was dropsy or constipation or if a female birthing issues?

there is a bit too much going on with not a lot of info(not your fault) it is difficult to determine what causes illness in fish.

keep up on the water changes and keep an eye on the cory. mo signs of infections(external) you may need to start looking at possible internal .
 
Make sure that your carbon is not old; it will leach chemicals and metals back into the water. When I forgot that I had carbon at the bottom of a HOB and finally removed it, my wife said "I didn't know that those fish were red."

I think it is more likely that your carbon was saturated and used up and not that it was leaching back in to the water.

Carbon can actually start to leach toxins back out into the water column if it saturated. I assure you that I am not making that up; google it for yourself and see.

I do not use Google to do scientific research. How about you find me just one article by scientist that shows carbon will leech out what it has absorbed in an aquarium. When toxins are "absorbed" by carbon they have actually become chemically bonded to the carbon.

I would just do a 25% water change, raise the temperature to 80 degrees and keep a close eye on them.
