I'm extremely confused/discouraged/angry and I need some help. I had 11 fish about a month ago...Diamond goby, two O. clowns, 3 saphire damsels, filefish, blenny, arc-eye hawkfish, foxface, and the latest was a hippo tang. I do weekly 10 gallon water changes, and I also have some inverts (shrimps, snails, crabs) and some random beginner corals, nothing fancy. It started about 3 weeks ago when I lost the foxface, goby and hawkfish in one weekend. Then it all went down from there. I was battling with some bad ich on the hippo tang and got it taken care of pretty well. Then after a few days it was back in full force. Then all but a few of the fish were losing their tail membranes...I assumed it was fin rot and bought Microbe-Lift Artemiss herbal treatment. I treated for a few days and fish were starting to drop dead. Lost the hippo, the damsels, and the blenny. I've still been treating and I lost a clown today...All I have left is the filefish which seems normal, and 1 clown which is acting a bit weird and lost some color. I've been talking back and forth with my LFS and they think it's some nasty strain of bacteria that has just wiped out everything. I did a freshwater dip today with the remaining clown so we will see how that plays out. Please offer up any tips and advice...I've lost nearly $200 in fish and I'm sick of wasting my money.
