Corrupt Goldfish

	Classic	Expert	Master	Legendary (For the Worthy)
Life	100	200	300	400
Attack	30	60	90	160
Defense	6	6	6	6
Knockback Taken	100% (High)	90% (High)	80% (High)	80% (High)
Coins	5	1250	1250	1750

The last column is Master mode in a world made with the For the Worthy seed. Its numbers were measured in the game, not computed here.

For one player in a world before Hardmode. Expert and Master scale life, attack, knockback and coins by the game's own multipliers.

Coins: each kill rolls the coins from 80% to 175% of this value, then rarer extra rolls can add more.

In a Hardmode world

On Expert and Master, a Hardmode world raises weak enemies: when attack plus defense plus a quarter of life is under 80 (100 after Plantera), the game multiplies them up.
