Ask Finn

Tiger barbs are energetic, striking fish with four vertical black stripes on a golden body. They are notorious fin-nippers when kept in small numbers, but large groups of 8 or more redirect aggression within the school and become safer community fish.

Care Guide

Diet

Tiger barbs are omnivorous and thrive on a varied diet of high-quality flake food and small pellets as staples, supplemented 2-3 times weekly with frozen bloodworms, brine shrimp, or daphnia. Include occasional vegetable matter such as blanched spinach or algae-based foods to support digestive health. Feed small amounts once daily, only what they can consume in 2-3 minutes.

Behavior

Tiger barbs are highly active, schooling fish that display constant movement and playful interaction within groups. They are notorious fin-nippers when kept in groups smaller than 8, but larger schools redirect aggression internally and become relatively peaceful community members. They occupy the mid-water column and prefer tanks with open swimming space combined with planted areas for shelter.

Breeding

Breeding tiger barbs in captivity is moderately difficult and requires separate breeding tanks with fine-leaved plants or spawning mops. Condition pairs with high-protein foods, then transfer to slightly warmer water (26-27°C) to trigger spawning. Parents will eat eggs and fry, so remove them immediately after spawning; fry are tiny and require infusoria or liquid fry food for the first week.

Treatment

Improve water quality with frequent partial water changes, reduce aggression by ensuring group size of 8+, use antibacterial medication if severe

Red streaks on body, swollen belly, loss of appetite, torn fins

Treatment

Perform 50% water change, maintain pristine water conditions, use broad-spectrum antibiotic treatment if condition worsens
