I am very new to saltwater tanks. I set mine up and bought an angel and a dog face puffer. Due to being ill informed, my tank started to cycle, and I had to bring my fish to a local pet store. So I cycled my tank over the next 4 or 5 weeks with live rock, live sand, and crushed coral. All my levels were perfect, and I had my water checked professionally numerous times. It was now time to bring my fish home. After about 3 days, my angel was lying on the bottom of the tank, breathing slowly, and occasionally having some sort of spasm. It eventually just stopped breathing and died. And it died pretty quickly. I checked the levels again, and all of them were fine. The puffer appeared ok just fine and was eating well. 3 weeks later, my puffer starting looking very stressed, becoming ALL black and hanging out at the top of the tank. I have been doing water changes and checking my levels religiously. 2 nights ago, my puffer did the same thing the angel did, and died as well. Does anyone know why this could have happened? Any help would be appreciated, as I would love to have fish in the tank I have spent so much time on. Thanks!
(I think my puffer developed ich in his last stages, but from what I've read, I think something else killed him)
