hello everyone, I'm rehoming my 6 black neon tetras, and have got an offer from an animal charity worker who seems pretty trustworthy. I just wanted to check that she doesn't have overstocking issues before going ahead with the deal. so, she has a 120l tank containing: Yoyo loach x1 Rummy nose tetra x1 Gold barb x1 Leopard danio x2 Cardinal tetra x 2 Bristlenose x1 Tiger barb x1 what do you think? (I know she hasn't got any substantial shoals but I believe that's why she wants my fish). thanks so much!
