I got four new Harlequins last week... Turns out 2 of them were lamb chop rasboras instead of Harlequins (I'm quite **** off about this)... The two tend to stay together but will sometimes join the Harlequins... I'm hoping they will do fine by being just twoAlmost 100% not. If so, I expect it to be for instance similar looking Rasbora like the espei.
