Ok, so im just wondering is there any reason why everything in my tank would be doing really really well: Corals, shrimp, snails, starfish, tube worms etc. Basically everything....apart from fish?!?! In the last few weeks (At seperate times and not added together) i got a black clown, Evansi Anthias, 3 firefish, a twin spot wrasse, a cleaner wrass, a sohal tang and a damsel of some sorts. All pretty small bioload for my big 325g system. They seemed to be doing really well for a few days. Swimming a lot. Eating everything i fed them. Then one morning i would wake up and i would find the fish dead and the shrimp eating them. Some of the fish would go for a week before dying. Some would die the very next day. Im stumped by this. The chromies and the largish yellow tang in the tank have been doing really well for months (chromies were the first fish in the tank). It just seems the newbies cant adjust very well. Im not detecting any signs of illness or disease and if it was something to do with my water conditions/parameters then surely the corals/inverts would be popping their clogs first, right? I did have a theory that it was just the shop i was getting my fish from that was seling me dodgy chinese rip off fish But the 2 latest fish to die were from a different supplier.
