Author: Mike - FishLore Admin
The Rosy Barb is also known in certain circles as the Red Barb and is a popular freshwater tropical fish that will bring a lot of activity to your tank. This fish is generally peaceful but like many barbs, can become fin nippers if they are not placed in a small school of 5 or more. They are also very aggressive eaters and will accept flake fish food with gusto.
Many have reported breeding success with the Rosy Barb by using broad leaved aquarium plants on which the female will lay it's eggs. Adults will eat the eggs so you must separate them if you want to raise the fry.
They will accept nearly all foods including flakes, frozen, freeze dried and live foods.

Rosy Barb Comments and Tips
|From: Dan A.|
I bought a couple of Rosie Barbs and they are very active. I'm just wondering if you could send some info on them and their behavior. Should they be with more of their species?
|Hi Dan. This barb can become a fin nipper if not kept in a small school. So, try to have 5 or more to avoid this fin nipping behavior. Other than that, they are generally a peaceful fish.|
|From: Robin - Rosy eggs?|
How long does it take before the females lay their eggs?
|They reach sexual maturity when they get to be about 3 inches in length. If the female looks like it's filling with eggs that means that it may be a good time to introduce a male. The length of time all depends on the state the females are in when the male is introduced. If the female is ready it could take a day or two for them to release the eggs. If you are interested in raising the fry you will need to establish a separate tank for raising them. The barbs will eat the eggs otherwise.|
