Soz, really need some help.

Have had Fish Tycoon on mobile for about 6 months, and on PC for about two weeks. Absolutely love it, but am FRUSTRATED!!!!!

Done lots of cross-breeding, and found five of seven magic fish, but now I've got SIX tanks full of fish and don't know which I dare sell, 'cos don't know which will help to produce last two magic fish!

Got the Spotanus, the Goldbulb, the Comet, the Grouper and the Fire-Arrow. Can anyone tell me the breed, and type, of the last two I'm looking for, before I go absolutely NUTTY!?

PLEASE?????
