I would realise my dream of setting up two tanks. One 150 gallon steampunk style tank, like an enormous victorian science experiment with bellows and great glass domes filled with plants and shrimp adjoining the main tank filled with endlers and galaxy rasboros with bronze cories for the bottom.., the other, a 150 gallon goth tank. Black gravel, black and silver fish such as Black Khulie Loaches, Black cories, silver mollies and lampeye killifish. I'd find some way of making ornaments in the shape of band logos. I think the sex Gang Children skeleton reaper would look splendid marching across the tank! A half buried Sisters of Mercy logo and a bust of Nik Fiend rising from the "grave" , being zombiefied! . Ahhhh if only.....
