Boy, did this take me back. Back, back, back like a swirling whirlpool wormhole of time transference to 1970, age 15, and I had discovered just such a place with outdoor ponds and square cement sunken indoor pools used for breeding tropical fish. In Bossier City, Louisiana where the giant AFB is, right next to Shreveport. The pools held betta fish. They did not use booze and they did not use hormones (that I know about) and the baby fish all over the place were the cutest little things.
And the next week we moved to Colorado.
That could have been my first job. GAWL!
