Cuming's Barb (Pethia cumingii) is a beginner-level freshwater fish that needs at least 20 gallons and 70-78°F. A small, peaceful barb from Sri Lanka with an orange-red wash on the males. It is calmer than tiger barbs, likes a group and a planted tank, and tolerates a slightly cooler tropical range.

San Diego water

Captive-bred stock usually adapts to San Diego tap water with slow acclimation. For best color and health, many keepers blend tap with RO/DI water. Learn the numbers in our San Diego tap water guide.

Before you buy

Make sure your tank is cycled (how to cycle a tank), check your numbers with the water testing guide, and use the compatibility guide to check tankmates. These are general ranges; individual fish and local water vary.
