minecraft:color2 can't be used without the tropicalfish runtime_identifier

Using the material tropicalfish doesn't work and gives a rendering error saying that the entity defines multiplicative tint but does not have a mutliplicative-tint texture, adding the tropicalfish runtime_identifier to the behaviour fixes that issue and makes the color2 work, but has drawbacks like the entity just starts to jump like a fish, can use a water bucket on the entity, and physics changes.
