Is it ok to have one green chromis?

I had three chromis in my fish tank but im seeing one that isnt gonna make it, all the rest of the fish are fine and ive been dealing with high nitrates. Seeing that one might pass is it ok if the last chromis be alone for awhile until we can buy another one?

yeah it should be fine.

Do you have a glass lid or an open top? I covered my tank and it resulted in really high nitrates, but when I uncovered my tank my nitrates were zero and I had to actually try to raise my nitrates.

Chromis in captivity will almost always pick each other off over time unless you have a really good size tank with a large school of them (ie 10-15). It is possible to keep just one, not sure how well it will do long term though.
