the best way i found to get the fish i want/need is to breed fish with the same 'fin', not by body

it took me about a minute to get the combo for this magic fish

wasp leaffish + wasp comet = wasp stickfish
wasp leaffish + wasp stickfish = wasp grouper

this was the last fish i needed to get all 7 magic fish...i was ecstatic when i discovered it so quickly.
