New cherry barbs all died
I went to the fish store on Saturday and bought 3 new cherry barbs. By Sunday night , all three of them had died. I’m just confused on how in less than 24 hours all 3 of my brand new fish had died. They all seemed perfectly healthy when I bought them. Hoping for answers.
I also had 2 cherry barbs in the tank already. Is it possible that they had something to do with the new ones dying?
I also have a pearl gourami. I know that these are peaceful fish, but could the pearl gourami have had something to do with this?
