Well, today's my birthday, so I get up this morning with a smile on my face. I turn on the tank lights, but don't really look at the tank in detail. I go back upstairs after a bit to check on the del, who was recovering from a couple minor scratches. Well, the del was almost back to normal, but my rhino pleco was dead. I don't know why, could just be old age. Are plecos sensitive to meds? I added some melafix/pimafix to help the del recover.
