here are some pictures to update you on what my 180 gallon acrylic tank looks like now. i changed out the refugeum to a 40 gallon. added some plants that are growing nicely. i also added some java moss to the drift wood. still waiting for it to grow. i got a new fish. a 12 inch sailfin i think ( the store called it gold dust pleco) not sure. but anyway i also bought a asian needle fish which was not a good idea with the oscars so now he chills in the refugeum with some rosy red minnows (food). i also got a free iridescent shark who is too small for the oscars right now so he is in the refugium too. Thanks for all the replys so far.
