I've had my maroon clownfish for about 13 years now. Throughout those years I cannot tell you how many other tank mates I've gone through. Many "mysteriously" perish within the first few days, while others sometimes last a handful of years. No rhyme or reason as to which tank mate my clown will accept to live with, his current tank mate is a pajama cardinal and they've been together roughly 3-4 years. I would like to add another tank mate but obviously want to avoid anything that would danger my current fish, but also don't want to just throw more money down the toilet. Any suggestions?
