Orthodontist Dr. Kawa has a simple request for the new addition to his waiting room aquarium: something "that no one has ever seen before." Jose and the guys have an idea, and it involves a "mermaid's purse." Using shark eggs that are rarely seen in fish tanks, Jose performs a surgical procedure of his own to create something truly unique. Then, the team is hired by one of the largest pet fish suppliers in South Florida to build a tank perfect for underwater gardening, or "aquascaping."

The FTKs are hired to create something completely unique: an African lake re-created in a tank swarming with freshwater cichlids and topped off with an African sausage tree. Jose has never seen a tree like this and worries that his replica might bring the entire project crashing to the ground. Meanwhile, setbacks plague a construction project to build a brand new, state-of the-art quarantine facility that will allow the Kings to provide a variety of fish to their clients.

The South Florida Science Museum enlists the help of the Fish Tank Kings to redesign 14 massive tanks! In addition to the sheer size of the job, the team will also be challenged to build something they've never built before: a canal exhibit, complete with invasive species such as pacu and snakehead. The pressure is on - the team at Living Color has just two months to finish the biggest, most intensive and most impressive job they've ever done.
