Hi. I bought 5 Chili Rasboras for my nano tank, and in the future ill buy maybe a little bit more. So my problem is that after I add the Chili Rasboras to the tank, there color were very pale, almost white. And even after 2 days their color is still pale. I know that fish lose color when introduce to new tank but even after 2 days they are very pale. Will they get there color back after more days? Or is it something else. btw Nitrite 0ppm, nitrates 0-10 ppm. I already had filter media that was in a cycled tank and I added some gravel from cycled tank so I think it should be cycled by now. Plus Chili Rasboras have a very low bio load. Can anyone tell what's wrong with my Chili Rasboras?
