Any specific benefits that would mKe it worth untimely to fish from wells?

thought someone else would have answered this.

There is only 1 advantage, every 15 fish levels, 1 tier of fish is removed from the list of fish you can get, so at level 15 fish in the fishing pond you'll be able to catch sardine, herring, cod, trout. From the well sardine would be removed. (note catching level 14 fish would result in sardine/herring/cod for both well and pond)
When catching level 30 fish herring gets removed from the list of catchable fish in a well

ahh kk so better loot from the well, as the bottom tiers are removed from the loot pool. thanks.
