Looks like an aulonocara ('peacock') and that particular variant is often referred to as Eureka, Strawberry, Sunrise or German Red.
Its a captive bred colour morph - developed in eh germany I think and very attractive fish. Keep with similar species (Malawi, peacocks ideally) in a large (over three foot in length) tank.
thanks Coler its cool to see an Irish fish keeper. When I was in Dublin in the summer I went to a little fish shop that was nice. My parents are from County Tipperary, Cashel to be exact.
