Sunday Post cryptic, 13 down. I got ideally, but can someone tell me what it has to do with fish. I can see Ally is friend, but I don't get the fish bit. I'm sure it must be obvious, but I'm baffled. Thanks.

Ide = Fish in general

Thanks scorpiojo and Mamyalynne. I'd never heard of that before. I'd heard of Ide as in Ides of March, but not as fish. Thanks again.
