Underground Sea Life and Warden Bait

So basically these are going to be small noisy and glowy fish that look a bit different than your normal sea/river fish.
These would be added in the large underground rivers.
If you found the small fish you could catch them to get some noisy fish or glowy fish.

Spawn rate 50/50.

You would be able to throw the fish. So you could use them like an emergency snowball, an extra torch, or a little touch to your personal aquarium.

But if the glowy fish is exposed to direct sunlight it will lose the glowy effect and become a normal fish(salmon or cod).
