I have 3 Zebra Danios and 3 Long Blue Fin Zebra Dainos. One of my Long Blue Fins is getting its tail eaten by the others. It was just a little but this morning more than 1/2 of it is gone! I am not sure what to do. The other danios are always nipping this one but not the others. All are females. Is there anything I can do for it?
