Hi guys, it's been a while but I'm baffled today...
I've taken on my boyfriends cory as it was being bullied in his tank. I've had him for over a month now and all has been well. He had some severely nipped fins and almost no tail due to the aggression in my boyfriends tank. Fortunately, his tail was nearly completely on the mend. He's been in the 70L with 3 other Corys while I nursed him back to health and upon checking up on him today, i found him floating on the surface, having his eyes pecked at by a Gourami who clearly thought he was dead. My first instinct was to move him upstairs temporarily into my 30L which is home to 6 Ember tetras and a Aspisdoras. He's been in there for about 6 hours now and although his gills are moving and he's occasionally swimming a long a little if disturbed....he clearly cannot swim well, which I'm guessing is due to swimbladder issues or some internal problem.
Whats confusing me most is the staining on his gills. It appears to be stained a yellowy brown colour which I know is typical of Nitrate poisoning. Due to this, I did a water test in the 70L that he came from originally and the readings are 0-0-20.
From underneath, the top area of his body under his gills appears to be somewhat transparent. I've taken some photos if anyone can give me any advice or guidance as to what this could be. I think nitrate poisoning can be ruled out along with any other sort of environmental poisoning such as deodorant etc.
I wonder whether it could be anemia or some internal parasite?
