did you cycle the tank??
the list you've posted is full of incompatible fish. frontosa grow to be large piscivores. mealnochromis and maylandia can be aggressive fish, and the haps might not get on well with that.
I strongly urge you to work out what you want from a tank, rather than throwing fish in. and choose species that are compatible together.
