Infection/Disease ID please

OMG!! What a disasterous day. I've been unsuccessful in catching those Black/White Clowns for a refund. I saw them attacking one of my smaller Orange/White clowns today. Then after I returned home from dinner my RTBA got sucked into the powerhead...<sigh>. I managed to carefully detach it, so maybe it'll still make it.
Anyways, I've been searching the forums and saw that some people had success using the inverted pop bottle method to catch a fish. Just wonder what type of food I can use to only attract the Black/White clowns? It would be a cage match if both types of clowns got in.

Thanks for any advice!
