If I had a dollar for every fish that has dead since starting this hobby I'd be a rich man. Don't know what the heck is going on system is running top notch crazy coral. Current tank mates include. Two clowns , fire fish , purple fish fire , mandarin goby , pink line shrimp goby, two lawnmower blennys "one in sump" ,4 dusky jawfish,sand sifter goby, royal gramma , scooter blenny. Not even able to count the snails and crabs 300 or so I guess ? Anyway last week blue spot jawfish crapped out after a month, along with a spotted mandarin goby , just bought a coris wrasse and he lasted about 12 hours AWSOME! Rest of the fish are all healthy so what's the deal. And I. Sure their are a lot of you out there with ten time the loss I've had ,just gets aggravating
