Hi, I have a Premium Black Snowflake clown that has been in the same tank for about two years. Its male counterpart died about a year and a half ago and she sat alone for 2 - 3 months. After I replaced him with a Gladiator (Both are ocellaris and he was smaller then her) and they were fine for the last 3 months until yesterday she started to chase him and nip at his fins. Today I found him dead. Is it safe to try to replace him with another clown or should I just rehome the black snowflake and restart?
