Hi there, i bought a rba about a month ago and it was doing fine. 2 weeks later my clowns were hosting it. But about 3 days ago it startet shrinking and it was revealing its mouth. Now it has shriveled up its feet and its mouth is still open and white, it also doesnt want to attach it self to a rock bc it keeps falling of. These are my water parameters: slinity 1026, ph is 8.2, alk is 7, nitrate is 5, phosphate is about 0.05 and my water temp i 26 degrees celsuis.
