Okay, it's going to be harder once school starts I will probably be using a site that hosts sims on it. I might make the art animated so the fish swim, flare, take a breath. Depends if the site can take animated art.
The site will be called "The Last Splenden" after horrible breeding, discovering of the Splendens, and YOU having to leave your home having a company build over the Betta stream, only 2 bettas were found.
Those are some of the hints I will give out :) Idea's will be well appreciated.
