I recently tried adding a midas to my tank. It worked great for 2 ½ weeks and then things got bad. My oscars were bigger than the midas but the midas was still able to pick on the larger albino oscar. When they fought the inside of the oscar’s mouth would get shredded. So today I had to get rid of the midas. I have a 210 with two oscar’s and a pleco so I had plenty of room and it still didn’t work out. Great fish but mean as hell. I have some good videos of them in my 210 page. All of the fish used to swim together. Too bad it didn’t work out.
