No problem.
As I mentioned, it's good you're already looking towards a bigger and only keeping the one black moor, as as they grow they can put a strain on a small tank as they are, comparatively speaking, quite messy fish and need a larger tank, strong filter, and regular water changes to keep them in the best health. I have kept moors before and they are attractive fish, just keep up on your maintenance. Their fins especially can be great indicators of your water quality - you never want to see them getting ragged and torn. Also, be careful if you have any plastic plants that may have somewhat sharp edges to them - eyes on moors are easily damaged. Best of luck!
