To properly acclimate fish open bag and pour fish and water into a container.
Pour water from your tank into the container in small increments. This allows the fish to adjust to any change in temperature. This whole process should only take about fifteen minutes.

How To Sex Tilapia
When a tilapia has reached about 3 inches in length it can be sexed by looking at the genital paella. This is located just behind the anus of the fish.
Male tilapia have a single opening, the females will have two.

Tilapia was a symbol of rebirth in Egyptian art, and was in addition associated with Hathor. It was also said to accompany and protect the sun god on his daily journey across the sky. Tilapia painted on tomb walls, reminds us of spell 15 of the Book of the Dead by which the deceased hopes to take his place in the sun boat: "You see the tilapia in its [true] form at the turquoise pool", and "I behold the tilapia in its [true] nature guiding the speedy boat in its waters."
Tilapia were one of the three main types of fish caught in Talmudic times from the Sea of Galilee, specifically the "Galilean Comb" (Tilapia galilea). Today, in Modern Hebrew, the fish species is called amnoon (Suggested derivative: Am= mother, Noon= fish.). In English, it is sometimes known by the name "St. Peter's fish", which comes from the story in the Gospel of Matthew about the apostle Peter catching a fish that carried a coin in its mouth, though the passage does not name the fish. While the name also applies to Zeus faber, a marine fish not found in the area, a few tilapia species (Sarotherodon galilaeus galilaeus, Paratilapia sacer, and others) are found in the Sea of Galilee, where the author of the Gospel of Matthew recounts the event took place. These species have been the target of small-scale artisanal fisheries in the area for thousands of years.
