Barbs

Minimum aquarium size will vary with species, although it is always best to choose the largest aquarium you can. Tiger barbs can do well in a 30 gallon or larger tank, whereas species like Tinfoil Barbs who grow considerably larger need at least 70 gallons.

Barbs do best in schools of 5 or more, preferably with odd numbers to prevent pairing. In an aquarium large enough for more fish beyond the school of barbs, they are generally compatible with other medium to large, fast-swimming fish that are not overly shy. Caution should be taken with fish with longer fins as some barbs may attempt to nip at flowing fins.
