Ichthyomorphosis overwrites all colors and creature types the enchanted creature has. It’s just a blue Fish. The creature keeps any supertypes (such as legendary) it has, as well as any other card types it has (such as enchantment).
Ichthyomorphosis
Effects that modify a creature’s power and/or toughness will apply to the creature no matter when they started to take effect. The same is true for any counters that change its power and/or toughness.
Ichthyomorphosis overwrites all previous effects that set the creature’s base power and toughness to specific values. Any power- or toughness-setting effects that start to apply after Ichthyomorphosis becomes attached to a creature will overwrite this effect.
