Hello, a while back i purchased a pair of blue throats. The male had a severe eye infection and died in quarantine after trying all kinds for about 3-4 months. The female was fine and was put into my display tank. Since then we have had two further males die in quarantine even though other fish were making it through. About five weeks ago,we got another male and he made it through quarantine and into the display. We sat watching to see what would happen and all looked well apart from our female clown nipping at him to keep him away which didnt seem to bother him at all. We went into the kitchen to eat and when i came back through to feed them,the female was attacking him. It wasnt just a case of chasing him off or pecking order stuff,this was a sustained attack to try to kill him. I had to literally fend her off with the tongs while i netted him back out and put him back in his quarantine tank. It is an 8ft tank so plenty of room etc. We had bought a longnose hawkfish the week after the trigger that was in a seperate quarantine tank so the week after,we put him in and observed again. Although she looked a bit aggressive toward him for a few hours,there was no attacking and by the day after she seems fine with him. So,i dont think she had turned into an **** that was going to attack any new additions,just another trigger! My question to everyone is,is she likely to do the same again if we tried him in again? Does anybody try this multiple times or is it a case of if she has done it once she will do it all the time with him? Is there any other things i can try or should i just get used to having a female on her own? Gutted,its taken nearly a year and couldnt have went worse,thanks for any advise or suggestions
