Tequila may not be the answer but it’s worth a shot.

Tequila Fish are members of the splitfin family are known as and endemic species (defined by their geographical location) in this case the Tequila Fish is only found in the American River Basin in Mexico. However with the introduction of guppies and the changing environmental factors their remaining population that was only found in 4m wide pool in Teuchitlan seems to have gone from the area giving scientists the belief they are extinct in the wild and announced so in 2013..

The base colouration of the head, body and fins are a dark olivaceous or milky blue-grey with bright flashes of ever-changing iridescence from mosaic scales. Females are more muted, lack the cream-colored edges of their dorsal and anal fins and have only a very thin, faint yellow crescent when there is any marking at all.

Unlike the rest of our fish there is very little known about these fish as they were discovered in the wild very soon before they became extinct. This makes it very hard to understand their behaviour and breeding however from studying the fish we can see that they are omnivorous and feed on smaller creatures.
