Barb Fish Species - Cyprinids and Freshwater Sharks
There are over 2000 identified species of the Cyprinidae fish family (the barb fish species) and the cyprinids are probably the largest group of fishes in the wild.
The water requirements varies from species to species with some such as the Goldfish and the White Cloud Mountain Minnow doing well in sub-tropical water temperatures. Some of these fishes get very large, such as the Tinfoil Barb and the Bala Shark. Others, like the Harlequin Rasbora and the Zebra Danio, stay on the small side.
Some can make good commnunity tank mates whereas others may not be the best choice in a community tank setup. Some that you should think twice before adding to your community aquarium would be the Red Tail Shark and the Tiger Barb. The Rainbow Shark can sometimes be very territorial as well. The "freshwater" sharks are listed here.
Balantiocheilos melanopterus Bala Shark Gets big and likes to be in schools making optimal care conditions difficult in the home aquarium.
Puntius titteya Cherry Barbs Males turn cherry red and these make excellent fish for beginning freshwater aquarium fish tank keepers.
Danio rerio Glofish The Glofish were genetically modified with the purpose to detect environmental pollution. Scientists were able to inject a fluorescent protein gene (from marine organisms) into the zebra danio embryos to create the glofish.
Puntius sachsii Gold Barb Another barb that is an excellent choice for newbies to the freshwater hobby.
Carassius auratus Goldfish The most popular fish of all time? Our old friend the goldfish.
Trigonostigma heteromorpha Harlequin Rasbora Looks fantastic in a heavily planted and kept in schools.
Cyprinus carpio Koi This is a pond fish and not suitable for most home aquariums unless you're wintering your koi indoors.
Puntius sp. Odessa Barb A beautiful barb that is quite colorful. Not very common at the local fish store.
Epalzeorhynchos frenatus Rainbow Shark Best kept as a single due to aggression with members of the same species.
Epalzeorhynchus bicolor Red Tail Shark Another "freshwater shark" that is very territorial and will not do well with other red tails.
Barbus conchonius Rosy Barb Also known as the Red Barb, this fish should bring lots of activity to a tank.
Pimephales promelas Rosy Red Minnow If being used as a feeder, they'll need to be quarantined, and medicated so that it will not pass on disease to your larger fish. It is best to breed your own rosy reds if you plan on using them as feeders.
Rasbora trilineata Scissor Tail Rasbora Named for the unique motion of it's caudal fin that moves like scissors.
Puntius tetrazona Tiger Barb A notorious fin nipper that doesn't do all that well in community tanks.
Barbus schwanefeldi Tinfoil Barb Likes to be in schools but gets too big for most freshwater tanks. The Tinfoil Barb pictured is a juvenile.
