Hey so I have a 200 gallon 24inch wide, 28 inches tall and 6 ft long. My current stock is: 1 albino tiger oscar 3 inch, 1 black tiger oscar 3 inch, 1 jack dempsey male 6inch, 1 green terror 2 inch and 4 silver dollars at about 2 inches. I was wanting a catfish/bottom feeder but I wanted to know if my tank would be close to being over stocked once they all reach full size and it would be unnecessary. Also being in Australia I don't have the best variety so out of choice I have seen normal Pleco which I would like to avoid, Pictus catfish, salmon tail catfish and an eel tail catfish. If any of these are okay or if you would recommend me not getting any I would like to know thanks
