I checked my params and everything is the way its been for the past 7 months. the only exception is the temp. It for some reason sky rocketed from 77 to 84. I turned the heater down (it's been VERY hot in NJ between 85 and 90 the past week) so now the temp is at 79 but the fish are starting to die one by one. Every morning i wake up and find another dead. They look almost like they suffocated if that makes sense. No signs of ich or stress my royal gramma was out swimming the next morning a gonner upside down almost looked like he imploded. next my shrimp, then my hippo tang and his cheeks looked almost purple like he had held his breath and died. my wrasse fish is breathing heavy and im afraid he's next. the only other strange thing is two dead snails and the shells are empty and my frogspawn looks like it has a HUGE bubble where his mouth is...it's super inflated and splitting as well? oh almost forgot! my short tentacle plate was brown and i changed my dosing and the beautiful green started coming back but now he's also purple? the purple looks more like algae that is growing in the tank and not its natural color! Please help peoples!!!! this has been an amazing tank for me watching everything grow. my corals seem a little stressed (not fully out) and my clowns are the only ones swimming around normally!
