Fairly disappointed overall

The app is called Fish Tank HD, but the resolution seems to be only around 900x512. Pretty much NOT HD in my book.
Secondly, the Fish Tank premise is pretty weak as well. Its common for a fish that fills the screen to come into frame from somewhere beyond the edge of the screen and disappear completely beyond the opposite edge! Not a convincing Fish Tank simulation at all.
A much more suitable title would be Video of Fish in Medium Resolution.
If the video was shot of a real aquarium, with the front glass filling the entire frame, it would achieve the desired affect, that of a Fish Tank with all the expected boundaries thereof.
I wish I had my buck back.
Oh yeah, and the sound is not very soothing at all either. But in fairness, I dont know what Id prefer in that regard.
