Variety of Rosy Barb · longfin
📍 India
The Longfin Rosy Barb is a fin-type variant with extended, flowing fins and the same rosy-pink coloration as the standard form. Hardy and peaceful, it schools nicely but requires tankmates that won't nip its fins.
Care Guide
Diet
Longfin Rosy Barbs are omnivorous and should be fed high-quality flake food or small pellets as a staple, supplemented 2-3 times weekly with frozen foods like brine shrimp, daphnia, or bloodworms. They also appreciate vegetable matter such as blanched spinach or algae wafers. Feed small amounts once daily, only what they can consume in 2-3 minutes.
Behavior
These peaceful schooling fish are most active and display best coloration when kept in groups of 6 or more. They are energetic swimmers that prefer open water but appreciate planted areas for security. Males may display mild aggression toward each other during breeding season, but overall they are gentle community fish that rarely harass tankmates.
Breeding
Breeding in captivity is moderately difficult and requires separate breeding tanks with dense vegetation or spawning mops. Condition pairs with high-quality foods, then introduce to slightly warmer water (26-28°C) with subdued lighting. Females scatter eggs among plants; remove parents after spawning as they may eat fry. Fry are tiny and require infusoria or liquid fry food initially.
Tank Mates
Similar size, peaceful temperament, and compatible water parameters make them ideal community companions
Peaceful gourami that coexists well with barbs; ensure adequate space to prevent territorial disputes
Schooling fish with similar size and peaceful nature; creates dynamic community display
Large shrimp less likely to be harassed; provides algae control without competing for food
Nocturnal algae eater that occupies different ecological niche and won't interfere with active barbs
Common Diseases
Ich (Ichthyophthirius multifiliis)
White spots on body and fins, rapid breathing, flashing against objects, lethargy
Raise temperature gradually to 28-30°C, perform daily 25% water changes, use aquarium salt (1 teaspoon per gallon) or commercial ich treatment; continue for 10-14 days
Fin Rot
Frayed or deteriorating fin edges, discoloration at fin margins, progressive fin loss
Improve water quality with frequent partial water changes, remove sharp decorations, treat with antibacterial medication or salt baths; ensure good filtration and avoid overcrowding
Bacterial Infection
Red streaks on body, swollen abdomen, loss of appetite, torn fins, behavioral lethargy
Perform 30% water change, treat with broad-spectrum antibiotic medication, isolate severely affected fish; maintain pristine water conditions during treatment
Velvet Disease (Oodinium)
Fine gold or rust-colored dust on body, rapid breathing, scratching behavior, cloudy eyes
Increase aeration, raise temperature to 28°C, perform daily water changes, use copper-free velvet treatment; darken tank to reduce stress on affected fish
