You definitely need to worry and do something NOW, if its not already too late? If it is a O2 / CO2 effect the gills / fish will recover fairly quickly once CO2 levels are lowered.Is it common for angelfishes or do I need to worry?
The blood is going to show more through the operculum in albino fish, but they shouldn't look like that. Try <"turning the CO2 down">,add an air stone (or raise your lily pipe etc) and see what happens. I'd also change some water. Haemoglobin in the blood transports both CO2 and oxygen, if the CO2 doesn't out-gas at <"the gill"> you often see this,I discovered that one of those angelfishes has lot of blood on its gills
OK that makes perfect sense and it will be because of high CO2 and / or ammonia poisoning in transit.They just came in less than an hour before my original post. So that coloration was already there, it's just that I noticed it in my tank.
That sounds much more promising, see how they look later.They don't look stressed, they are exploring their new home, eating, looking at the landscape even before I changed the water, and raised the lily pipes.
CO2 in drop checker is still Dark Green (not even closer to yellow) so I am not sure if it's high. But I did reduced CO2 to mere 1 bubble in 3 seconds. Besides angels I also have a pair of Siamese algae eaters and 2 Bristolnose Placos. These fishes immediately started doing their work after entering my tank. Though I am bit worried about my second Bristlenose Placo, I haven't seen him ever since it went into my tank.Hi all,
