I'm calling having an Elephant a Chimpanzee and an Octopus for my 3 main assistants.
Th Elephant for all those super large incredibly heavy boxes, like new hull plating. The Chimpanzee because their stronger then Humans and I need someone else capable of moving heavy equipment around. The Octopus for checking water based containers for various things, including water quality, that would be important, though we probably have machine's for that... Maybe we should have a small aquarium, it WOULD be a good idea to have some sources of food on the ship that have some ability to replenish themselves...
Hmm...
A small cube of ship space dedicated to basic food production, in the ships allotted storage space, 29 meters is slightly more then 95 feet so we should have room... 5 Floors, the top floor dedicated to Trees, fruit bearing trees, floor is subdivided into four 'sections' for optimum temperature and light and water, this is for trees that grow in different seasons or climate's. The Three floor's below that are for basic farming, mostly vegetables but the top one of the three floors is mostly fruits, these floor are only just tall enough for someone to walk around checking and doing necessary farming. The bottom two are an aquarium, this was decided because fish can't escape an aquarium, the Octopus assistant is in charge of the bottom two floors.
No we do NOT keep sharks in the aquarium, most likely it would be water lifeforms that supply a decent amount of nutrients and maybe 1,2, possibly 3 species of fish that breed and multiply REALLY fast. We may have Crabs Lobsters Crayfish and Shrimp though, they are pretty effective cleaners, and if you include a lot of food (Plant's and small rapidly breeding fish, like guppies) and don't put in anything that eats them we could have a decently stable population of them... Plus other basic things like sea snails and maybe clams and mollusks...
Wait sorry I should ask first... I get a little carried away in project's like this.
