I got 10 ember tetras a few months ago (maybe 4 or 5 months) and now i have 1 baby ember. Does anyone know on what scale ember tetras are in terms of producing babies? I am wondering if I should wait before introducing a different group of tetras or if the ember tetras will basically fill my tank's capacity within a year. I am still traumatised by guppies...
