Hi I've got a 70 Gallon tank its 4ft long by 19inches wide. And I have 2 blood parrots a jack Dempsey and a pleco. Im new to keeping cichlid's and was wondering if there would be enough room in my tank for dither fish and if there is what kind if any fish would work as dither fish. My blood parrots are around 5 inches and are still very shy and my jack Dempsey is about 2 inches. Thanks
