I just got an 80 gallon aquarium from my sister-in-law who didn't want it anymore. It took over 1/2 a day on Saturday for us just to get it broke down and moved along with all the fish. Of course I don't want to keep ANY of the the fish she had. I lost about 12 of the 95+ platies in the move but everyone has been fine since I put them back in the aquarium after moving. The gourami's are about 6 inches and are big enough to creep my shelties out when they stare at them.
I'm in the Fort Collins area. I would charge $2 each for the gourami and 25 cents each for the platies. Or trade for some plants and/or corydoras/bristlenose catfish or small angelfish.
