Green Severum turning color?


I have been keeping fish for a while now; about 15 years. I have just recently purchased 2 green severums and it is the first time I have ever had a severum. They are both about 3.5" and are in a 110 gallon tank with 3 small blood parrots (about 3" each) 8 Giant danios, 6 hatchet fish, 2 bristlenose plecos, and 8 Corydoras. So ar, they are doing great, I have noticed no aggression between them and the blood parrots and they are acting and eating fine. My water paramaters are perfect with ammonia =0 nitrite =0 and nitrate =10ppm. My question is this; one of the severums periodically turns from the normal pale green color to a very very dark blue, almost black. next day or sometimes just a couple of hours later it is back to its normal color and then will change back again. I can't figure out what is causing this color change and if it is anything I should worry about. Any help would be greatly appreciated.

Thank you


welcome to Fishlore.

I've got a young Green Severum and he will change color depending on mood; fade or darken. Nothing to worry about.


I agree, I don't see anything to worry about. I have a couple young green severums as well and they change colors all the time. I don't see any aggression or stress with mine and they still go around changing colors.

So sounds like it is pretty normal then. Thanks for the replies.
