Looking for new frog/frogs

[Dace]

So many care sheets I've read suggest the very minimum size of tank for any animal. When buying larger tanks than suggested, you're actually doing yourself a favour as well as the animal, as the substrate doesn't spoil so quickly and as a result, a complete tank clean out doesn't have to be so frequent. An animal could show stress with irregular activity for the animal, snout abrasions, going off food, decline in health, etc.

Are irregular activity and snout abrasions not the same thing as trying to escape and decline in health and appetite just a given?
