If you get a salt water tank system in your house

hire a specialist to take care of the tank, its a full time job

if money is no object

build a room just for the care of the tanks

you will need more than one

my daughter was a wreck bcoz her yellow fish the kids named Dory was sick and dieing and she did everything right

it wasnt pretty on the tx with the 'pet world' owner trying everything but
cottage chees and raw hamburger for the pretty yellow salt water fish that died in front of the children OMG!

then the rest of the OTHER fish in the salt water '2 hundred gallon octagon shaped tank' freaked out and they died

moral of story

watch Nemo the movie

its really cute
