Fish game
 

Looking for a PC game from the early to mid 90s. You made your own fish, squid, etc. You swam around eating other fish and stuff and upgrading your fish. It's not EVO, though that's a good game too. My friend and I were reminiscing and we think it's either called *blank*'s Aquarium or has "Coral Reef" in the title. I remember you could play as a grouper which could eat just about anything but the giant clams.

Couldn't find anything about Coral Reef or the former.. But it sounds a lot like Odell Down Under from MECC.

El Fish ?
