Some back story is I use to have a 5.5 gallon planted snail tank, well I found a 5 gallon metal rimmed tank and moved my plants and snails over to said plant. I got a new filter but seeded it with my old filter from the 5.5 gallon. I have been testing my water and my parameters have been great for about 3 weeks now. I have some small fry in there now that i'm in the slow process of removing. I still don't know why but I lost my mystery snail and one ramshorn snail. All my other ramshorn snails are reproducing and acting normal, the fish, MTS and pond snails are also acting normal.
So how mature does my tank have to be before I can add the shrimp residents?
