Is This Really True About Betta Fry?! (PLEASE HELP ME!!!!!!)?

Feed them lots of baby brine shrimp, do frequent water changes and in 2 or 3 months they will be nearly half grown. It is also important to keep the males separated from the females and from each other - each male will need his own container or jar for the rest of his life so be sure to get lots of jars. I use one-quart mason canning jars You can tell the males because they will start fighting as soon as they recognize each other as male, and when they do you must separate them. Normal spawnings are about 150 babies and if half are males you will need 75 or 80 jars. I had some success with a 70 gallon tank where they had a lot of room and didn't fight as much.
