Water parameters
Overview
The Java barb is an important food fish widely farmed in ponds and rice paddies in Southeast Asia. Juveniles of its silver, gold and albino forms are sold in the aquarium trade; but adults reach 35–40 cm. Like the tinfoil barb it has a deep, laterally compressed body, but its fins are gray-yellowish rather than red. It has been introduced to many countries for aquaculture; aquarium fish must never be released into the wild.
Tank Setup
- At least 1000 liters and 200 cm in length for 5–6 adults; in the long run a large indoor pond is more suitable.
- 24–27°C; powerful filtration, high oxygen levels, a 30–50% weekly water change.
- Simple decor: roots and large rocks; plants are eaten in a short time.
- It jumps powerfully; a heavy, tight-fitting lid is essential.
Diet
An omnivore that feeds mostly on plant matter. Use spirulina pellets, blanched vegetables, lettuce and spinach as the staple; supplement with granules and frozen foods. It also eats small fish and shrimp that fit in its mouth.
Behavior and Compatibility
A peaceful but very fast and large schooling fish. It does not attack fish of similar size; it sees small species as prey and stresses shy species.
Good companions: peaceful giant fish of similar size: tinfoil barbs, bala sharks, large plecos, large gouramis.
Avoid: small and medium community fish, dwarf shrimp, planted tanks.
