Yes, can think of lots of fun
or even useful
things to have...need
is something else, and afford
is where reality comes crashing in again.
Just being alive and healthy with clothing
on my back and food
in my belly is fantastic, anything more is a bonus.
Still, I love aquariums. A buddy of mine on N Stradbroke Island built himself a huge timber house. He installed a 3m saltwater fishtank to hold fish
that he found or caught. His thinking was to be able to have fresh fish
when he wanted a nice snack. "You don't have to be hungry to eat", was one of Tim's favourite sayings. Worked fine until he put a mudcrab in there. It snipped up some of the fish and it all rotted and he had to start again. Pity; he had a lovely red emperor in there at the time. Beautiful fish, a shame really to eat it.
I only ever had a freshwater tank. The dwarf gouramis were the coolest...smart little fish, they figured out how to rinse crumbs of food
off the glass above the water
when it stuck there at din-din time. The archer fish was neat...I cut the barb and point off a dry fly and hung it over the tank; he would take potshots at it for hours, and hit it every time. Not sure if I'd risk an aquarium on a boat
...I suppose a gimbaled tank mounted down low would be safest, but too much trouble and potential for disaster. I've seen viewing ports
built in hulls but don't like the idea of such a weak point, cool as it is. Viewing tube and snorkel will likely be the limit. I wonder if one could colonise one's hull
with useful sealife rather than permitting random growth. Or find some lifeform that doesn't bring a drag penalty with it. Hmmm, I wonder if anyone ever tried mother-of-pearl as an antifoul coating?
