Sharing my experience with this product.
Recently one of my mid size female ray was harassed pretty badly by my just matured male. Bitten quite badly and was doing Chin ups throughout the whole night. Heavy breathing and not feeding for a couple of days.
As adviced by Max, separated the horny male, dosed mirage vita. The next day she started to nibble on mp and few days later took 1 whole piece of mp and now appetite is more or less back to usual.
