Dragon fish

The dragon fish should spawn in the deep ocean biome when it's day time they will hide in a cave underwater but if it's night time they will get out but they will stay in the depths and if they see you they will attack you. the useful thing about them is when you kill them you get their light source which is gonna light better than sea pickles but not much from sea lanterns if you place them out of water however they will dry out which is gonna be 3 stages for it when it reaches the final stage you don't have any way of fixing them you will have to find another one. but they need to look terrifying
