They are neonRemind me what type of tetra's you have?
I had planned to do that when my tank was clear of white spot but the last three have died this morning so I've now an empty tank. Definitely going to use the advice of people of her from my previous posts and I've spoken to my pal who's had years of experience with tropical fish and she's given me a few options of what I can have comfortably in my fish tank as wellI would up the neons to 6, they are happier in schools. Then you would have room for some snails or some pygmy corys (also need 6+).
