I was getting stuff packed up for a little trip tomorrow when I heard a "pop" from the other room. Checked it out and my little azure was stuck in the intake of my skimmer : / It was a pump getting clogged noise, not a mantis type sound.\n\nI've checked my water parameters and this is what I have right now:\npH: 8.2\nAmmonia:0\nNitrite:0\nNitrate:10-15\nSpecific gravity:1.026\n(Using an API test kit)\n\nHe'd been doing great. I fed him this morning and he was quick/alert, I didn't see any signs of this. Frankly I wasn't ready for him to die! Ugh, glad I'm not going to be home tomorrow when my 3 year old wants to help feed him...\n\nThe ONLY thing I noticed about him was that he was a slightly different color than his buddies. His belly was not quite as bright yellow. I inspected the body and it was pretty fresh, no signs of anything abnormal.\n\nOnly changes to the tank in the past few days was a 20% water change yesterday. I let the salt mix almost 36 hours before it went it, temp checked it, salinity was the same. really don't understand what went wrong.
