All started when I bought four tiny fresh water lobsters before a year, now there is only one left, of course these new inhabitants ruled all over my aquarium and ate around 20 of my tropical fish( I used to feed 'um fresh snails from my garden, sea snail, small crab & tiny fish from the sea) while they grew they started engaging in fights till one ruled the aquarium alone. Now this one enjoys playing with dummy fish & other decoration in my aquarium. Follow me on Youtube: http://www.youtube.com/watch?v=a46lpdKhZ5Y&feature=mfu_in_order&list=UL
