Hi, this is my 1st ever time of posting a thread so please forgive my ineptitude. I am a relatively new aquarist, I have had a 3500lt marine aquarium for about 9 months now and I'm always in the market for advice and tips. My little marine eco-system has a variety of hard and soft corals, fish and other invertebrates.I have had some success with corals and fish but I have had a problem with Antheas first my male and then my female appeared to have some kind of fit which left it with a protroduding mouth, this happened on a couple of occasions before each eventually died. Can anyone help?
