Breeding pair of Midas, tank size?

in the future you would need a 125g but a 75g would last a while.

A 75 would be pathetic. A 6x1.5 ft footprint is minimum for two 12"+ fish. The bottom appears to be the female, top male. Face structure is different with Midas, meaning male and female have different faces. This has always worked for me.
