Gulf Stream Aquaria - Deep Freeze Tweaks

A simple mod altering a few aspects of several fish and invertebrates in the Deep Freeze DLC. -Moves the Antarctic silverfish, Arctic char, Atlantic halibut, barreleye, black seadevil anglerfish, long-nosed chimaera, Pacific viperfish, and shorthorn sculpin from their official categories to more granular ones created by prior mods. -Makes the Arctic char freshwater-compatible. -Makes the giant isopod and bubblegum coral able to be placed in non-abyssal tanks. NOTE: Due to the final mission of the Deep Freeze DLC campaign only counting abyssal-exclusive animals for one of its objectives, this mod will make the mission unbeatable using just default animals. Either disable the mod or add extra abyssal tank-exclusive animals from mods.
