When i will know if my longFin Rosy Barbs is pregnant?

Question

What i must do if she is pregnat. the other fish will eat the eggs or not.

Answer 1

As the first answerer said, barbs are egglayers, so she isn't "pregnant". If you have a male, you can try to spawn them, but you;re better off to do this in a separate tank because the other fish will eat the eggs (and the parents will too!). The easiest way to keep at least some of the eggs from being eaten is to put them into a small tank that has layers of marbles on the bottom. The eggs will fall down betewwn the marbles where they'll be safe, but can still be fertilized by the male. Afterward, you can put the parent back into the regular tank and wait for the fry to hatch. Here's a link for you on how to breed them if you do have a male: http://maximwebsite.tripod.com/rosybarbbreeding.html

BTW, barbs are a schooling fish, and should be kept in a group of 6 or more of their own kind.

Answer 2

Longfin Rosy Barb

Answer 3

not pregant but full of eggs, you will need a male if you want offspring. all the fish will eat the eggs including the rosy barb. if you want to keep eggs you should breed the fish in a seperate tank and remove them once the eggs are laid
