Today I was at my pearents beach house and I was turning over rocks with my nephew and I was alwaying finding these cool little fish some where bright green some where dark brow with white bands i think they are some type of benniles(spelling?) and some cool eel looking fish...... and a bunch of little shrimps I think it would be a cool little tank may even add a few crabs u never know.............. i think it will be in a 10 gal tank with a hob filter the main this is i have never owned a salt water tank ever! so i dont know how to do water changes and i dont live near the beach so id have to get like the salt from the pet store? and how would i mix the salt into the new water...... wat im saying is i have no experince with salt water and just teach me the basics of salt water like how to do water changes and all that.......
