I am considering a single predatory fish habitat. Tank is 48"x24"x28"h. My species of interest would be a Jag,Dovii, or Umbee. Keep in mind only one of these fish will be added. Can any pleco's,catfish, or silver dollars survive with one of these fish. I am also open to options on the predatory fish.
A 150 would be perfect for a male Jag. The SDs would work, too. a pleco might find trouble in a 4 foot tank with an aggressive male jag. Could work, though.
