By waiting for the apex of a motion, Angkatavanich captures striking portraits of otherwise humble fish.

The photographer's interest in bettas and goldfish began because his father regularly bought them for him as pets.

Angkatavanich compares the motions he's looking to capture to those of graceful dancers.

After each shoot, Angkatavanich adopts the fish as pets.

Occasionally, someone beats him to the fish he wants. "hat can make me feel very upset the whole day," he says.

Some digital retouching is used to clear the errant fleck of dust.

All photos are shot in the photographers home.

The unnamed series has around 300 photos in it so far.

Critical to getting the right shot is making sure both the tank and the water are absolutely clean.

The photos are taken with simple equipment, just a D800, a simple strobe and various lighting arrangements.

Spending hours sitting down, the photographs are as much a product of patience as preparation.

The photographer visits pet sellers often to get first dibs on the most colorful and graceful fish.
