Dunno if this is doable or not but...
After being oddly entertained playing Insaniquarium & after reading a thread elsewhere that said "if u could create ur own fish, what would it look like?", I began to think "wouldn't it be cool if Reefuge members could have a virtual aquarium in which they can create their own fish "avatar"?. Then I further thought that members could earn/unlock upgrades for their fish along with or instead of trophies for posts. Like: 200 posts let's u choose from 3 colors for ur fish but 400 posts unlocks 7 colors to choose from. U could customize scale, fin & scale shapes & unlock better options according to ur activity on the forum. It'd b cool if they could interact like in a chat room or online game. Perhaps instead of just a list of names showing who is logged in on the forum, u could see a small aquarium as well with each fish avatar appearing when each "owner" logs in. Perhaps further features would involve "breeding" ur fish & other features like that facebook farm game. I have no idea of the technical difficulties or logistics - I failed computer coding in Yr 12 & while I can operate most devices, I wouldn't have a clue how to BUILD them *sigh* anyway, it was just a passing thought.
