+1 to this, nano just means small tank volume. Dimensions will be better than volume in this case.What size is that nano?

This has also been my experience. I think the male helps temper the female because it gives her something else to focus her attention on, and he can handle the abuse.A pair is less aggressive from my experiences. My female got very aggressive when she was widowed, but when I put a new male in, she was very peaceful.
I think it would be a tight squeeze in a 15 in my opinion. I would do the helfrichi with some other nano fish and rehome the clown. There are loads of great nano fishy out there, some with super cute personalities.Do you think I could add a male clown AND a helfrichi to put the aggression off of the latter?
Too much for 15g. You could add a male clown, goby or blenny though.Do you think I could add a male clown AND a helfrichi to put the aggression off of the latter?
