Wishiwashi's competitive identity is built around Schooling. It transforms into a powerful school form above 25% HP, which changes the math on what Wishiwashi can and can't do in battle. Only weak to Electric and Grass. Part of the Gen 7 roster.
You won't find a real weakness in Wishiwashi's stat line. It's well-rounded for the Small Fry Pokemon, and what it does with that depends on moveset and items. Yields 1 HP EV, on a fast 800K XP curve.
Weak Wishiwashi school together to concentrate their power. Their united force makes them the demon of the sea, feared near and far.
At their appearance, even Gyarados will flee. When they team up to use Water Gun, its power exceeds that of Hydro Pump.
Wishiwashi Weakness
GoodType-wise, Wishiwashi takes extra damage from Electric and Grass. The Water typing picks up 4 resistances to work with. Wishiwashi's Water typing only leaves 2 gaps to cover.
No evolution chain to worry about here. Wishiwashi is a standalone Pokemon with no compatible partners for breeding through one egg group. Eggs come out quick to hatch.
How to Evolve
Breed Wishiwashi easily from the Water2 egg group. Pass egg moves like Mist, Muddy Water, Water Pulse and 1 more to offspring.
This build takes hits and hits back. Leftovers provides passive recovery each turn, Schooling supports the gameplan, and max HP and Attack EVs mean Wishiwashi doesn't crumble to chip damage. Plus Ground coverage backing it up.

The egg pool carries weight here. Mist and Muddy Water aren't available any other way for Wishiwashi, and they meaningfully change what it threatens. Stack those on top of Hydro Pump and Aqua Tail for solid options.
