Your over complicating things lol. First off yes you can use latex gloves in the aquarium, just rinse the corn starch off them before you put them in the tank as a large amount of it can make your skimmer go crazy for a day. But why not just bare hand it, its not going to bite lol. Also you can remove it from the tank as long as it stays moist/damp on the outside your not really killing anything. So hope this helps out a bit. Once its outta the tank you can drill it, stack it, zip tie it, epoxy, shove pvc
pipe through it, or whatever you can think of to make the desired look you have in your head.
