I am new to having fish. I have a local fish shop owner cleaning and taking care of my tank. He is also a personal friend. I have a 75 gallon tank with liverock. My tank has been set for two months and just recently had two fish added. We added an adult heniacous and a fox face. I realized after a few days that the heni was not eating and noticed that his body was getting black sores on it. To make a long story short the heni and the fox face both died. The owner said there was probably a bacteria infection that contaminated the fish. He treated the water with some sort of antibiotic.

After several days and after a water change and water testing we purchased 3 small heni's. The next day we noticed a blood spot on the side of one of the henis and found himm on his head still alive. I attempted to move the crabs away but it was too late, the crabs ate the fins off of the fish and the fish later died.

This morning I woke upi to check on the other 2 and we found one dead at the bottom being eaten by crabs.

If that was not bad enough, I received a call from my wife saying she went to check on the last fish, but it was already dead and eaten too.

Right now we are pretty frustrated beacuse we have spent over 100 dollars in fish that had only lasted 2 weaks. Could something be wrong with the water? Are my crabs too aggressive? Or is this normal when starting a tank.

Does anybody have any suggestions?
