I am going to get 6 harlequin rasboras, to go with my male betta in a heated, filtered, and planted 10 gallon tank. how do I quarantine them? I only have 3 1.5 gallon tanks I could use to quarantine them. Can I put 2 rasboras in each 1.5 gal tank? or all of them in one? Or should I do something else??
