In my 4ft tank I have guppies mollies swordtails endlers platys breeding plecos and corydoras, are a breeding group of rosy barbs with fry suitable for this tank? I've been offered them by my friend who is closing his tank down? Thanks
It depends on how many fish you already have in the tank, rosy barbs can get to around 5" so if you take them you may be overstocked.
The fry depending on how big they are may end up being tasty snacks for your livebearers
There is a separate tank for fry as I get babies from my livebearers, my tank isn't very stocked and at present is around half stocked. I was more concerned about issues such as nipping
