Hi there, thanks for your report!

The Fishious Rend bug has already been reported, and is pending atm. Keep an eye on this ticket for updates: tracker.php?p=2&t=16615

As for the Sparkling Aria bug, I can confirm this to be reproducible, so I'll go ahead and send this onto internal. According to Bulbapedia, Sparkling Aria should "inflict(s) damage to all adjacent Pokémon, including allies." At this time, Sparkling Aria only hits the intended target.

Thank you!
Katzyn

Moved to internal!
