1. Betta Fish (Siamese Fighting Fish)
Betta fish are undeniably one of the most popular choices among aquarium enthusiasts. Known for their flowing fins and striking colors, these fish are true showstoppers.
Why Bettas Are So Popular:
Bettas are often referred to as “living jewels” because of their iridescent scales and elaborate finnage.
