Neolaprologus types
 

Neolaprologus brichardi, Neolamprologus pulcher "daffodil".... I have these types of fish in an aquarium i dont know which are which the ones that i thought were the daffodil look like the ones that i bought 6 months ago as brichardi and the recent ones that i bought from big als look like picks of the daffodil but they said they were brichardi so i have a tank of mixed but i am wondering if they will cross breed and pair off? thanks

Daffodils will show a much more prominent yellow on the fins.
