Help please! Noticed around 3-4 days ago that my Neon blue striped mushroom was shrivelling up which it has never done in the months that i have owned it. Checked all parameters and everything is great so i thought it was just having a moment. Woke up this morning to just about everything in the tank looking quite sick. The normally happy elegance is closed and swollen, my frogspawns, hammers, blastos etc havent Opened and look terrible. On the other hand my bubble and leather are loving life. Parameters, light and temp have all been the same for months. The only thing i have moved is a fungia, Everything is how it has been for atleast 5 months. Ive done water changes and changed some filter media+ Added carbon but everything is getting worse.
