Ha thanks, but I really doubt it, I just google'd 'killifish pictures' (I knew I had seen that fish before, and my reasoning went that 'if I had seen that killifish, it HAS to be a common one', found a picture that matched it and put the name down here ).
EDIT: I did have an cap lopez lyretail for about 2 weeks, but the lure of big fish wins over beauty and colours for me unfortunatley
