I do have them high up in the tank. I didn’t see anything on your page about them to explain this . . . Fish appear to be fine, and the Eiblii and flame angel seem to be oblivious of each other (they were in separate tanks prior and I was afraid they would fight) although they are picking the rocks a lot — I think because there is not as much algae as either one of them are used to. Coralline algae is covered with green (which I attribute to their fresh-water bath during my beloved hubby’s frantic attempts to save what he thought of as alive — fish and corals — with the saltwater) I thought perhaps I was getting some die-off, checked all readings this morning: ammonia, nitrite, nitrate, phosphorus 0 pH 8.1 alk 3.5 calcium 250 Seems to me the numbers are going the wrong way . . . I am trying (-: to be patient with this 2 part but I am not sure it is working . . . me being patient, I mean, LOL.
