that looks like my hygrophilia polysperma and it is normal for it to offshoot several times from the stem and u are lucky if that happens becasue then u can get like 5 new stems out of 1. just replant it and watch it grow. this plant is amazing. it grows like a weed but is a really nice plants if u put little bunches of like 3-5 stems together. but only do this is u have decent lighting or the bottom of the stems will al die and rot away.
