Will these fish be ok together?

Ah I see.

5 harlequins total, or five in addition to the four you mentioned at the beginning of the post?

sorry, i meant 4. i just wanted some top dwelling fish for my tank, so the middle-bottom isnt overcrowded. will it be ok?

should be ok...obviously only providing your filtration and maintenance are good...I'd get six harlequins though, they like the biggest shoal possible.
