Moved Blue Crayfish to tropical.

Changed red swamp crayfish to fireback crayfish (There's already an amazing red swamp crayfish in the workshop, go check it out! Way better than mine :) ) and majorly tweaked the tasmanian crayfish around (size and several other thingies)

Fixed the red crayfish

Updated textures, removed signal crayfish and added tasmanian giant crayfish instead. Enjoy!
