I was given a 29 gallon tank yesterday that included an 8 inch oscar and two full grown three spot gouramis. (The 29g tank is for an upgrade on my 10g nano saltwater tank).
I moved all the fish I had in my 30g tall into other tanks before adding these three new fish. The gouramis will be given away asap. The oscar will going into an empty 55g within the next few days. I drained all the water last night and need to replace the gravel and do a major cleaning before adding him.
I probably won't keep the oscar since I have plans to turn this tank into an mbuna tank but I thought I would post a picture anyway.
