This is for 1 Celestial Pearl Danio (Danio margaritatus) Aka Galaxy Rasbora. As with all my other fish these are tank raised and bred with multiple gene depth for future breeders and better quality. Easy to keep fish hard or soft water. They do prefer shallow and small tanks but do well in big tanks as well. Great community fish as long as it doesnt fit in any of the other fishes mouths.
