My albino cory is spending alot of his time blowing bubbles around the parimeter of the tank and is showing dark areas inside his abdomen. He doesn't seem to eat like he used to and seems a bit slim compared to my other corys. I'm a bit worried particularly about the dark areas inside his body. Has anyone else had this issue before?
Is my cory sick??

My filtration seems to be good. My other 2 corys seem good, active and eating with an occasional trip to the top for a single gulp. The dark areas in his belly concern me. I had my water checked and everything is normal. My tank just finished cycling a week or so ago. I had moved up from a 5 gallon to a 21 gallon. I have an algae bloom going on that I am having a hard time clearing up. I did use a hagen coagulant which helped a bit. Maybe he is sensitive to the algae or the coagulant?? Any thoughts?
Cory's Gulp Air period. It's in there nature. If you don't have Cory's doing it something wrongDarkEntity said:

. "Gyrodactylus spp. (Category A.) These monogenean parasites have only been found on the skin but they are often present in significant numbers. They are vivaparous or live-bearing and so when conditions on the skin surface are suitable eg. when there is skin damage, and especially when the fish are stressed, they can very rapidly build up in numbers. Gyrodactylids are up to 2 mm in length and can readily be distinguished from other monogeneans in skin smears under the microscope, by the absence of eye spots and the occurrence of the embryo in the mid-region of the body (Fig. 4). They are often quite active on examination and readily seen under low power magnification. They can be responsible for massive losses when, under as yet unexplained circumstances, a sudden population explosion takes place in apparently healthy fish. Affected fish, of any age, but generally young fast growing stock, have dark patches over the body surface, with sloughing areas of skin. They generally do not feed, and the parasites can be readily seen in skin scrapings, often accompanied by trichodinids."
sounds a little extreame... but it fits, see if you can quarintine it...
or hes constipated or something... see if it east de-skinned peas
