So I’ve had this pair of clownfish (long fin and black storm). Up until this point they have been paired and have had no issues with them for 10 straight months. All of a sudden the female (black storm) started attacking the long fin, I didn’t think too much of so I left it alone but the next morning I woke up and found the male (long fin) ripped to shreds. I quickly took him out and brought him to my friends tank but unfortunately he didn’t make it. I am now just very confused as to why this even happened like I said they have been paired and had no issues for 10 months and this sorta just came out of no where. Did I do something wrong? Is there why thing I should’ve done? Any advice on what to do with the lone female now? Anything helps.
