Yesterday my clown goby sadly passed away after becoming lethargic and left it in a plastic cup. After a couple hours i came back to bury him when i saw an isopod looking thing attached to his eye. Today a couple hours ago my cleaner shrimp died with no apparent reason and also has no isopods or bugs on him. My parameters. Temp: 78 alk: 7 nitrate: 20 ph: 8 i am doing a water change now to help if there is an ammonia spike
