I found them at the local fish market and they are used as a live food for huge Arowanas . I got 10 in my 70 l tank but I don't know anything about them. So far I think they ate all my snails which is great :rock: They told me that they are native to Cambodia but language barrier didn't allow me to find out more. Fish are beautiful and nice behaving so I guess there will not be a problem to keep them,but I have this old habit to know any species,plant and fish, in my tank so please,if anybody know something (scientific or common name) share with me!
