I have a cool little 18g with a 4g raised in-line sump. The main tank has a feisty orchid dottyback and the little tank has a tiny blenny. I know im about maxed out on fish, but id love to add another to the main tank that has some character. The tank is about a year old. Parameters are pristine and ive designed it for a huge bioload. I have a big CuC, dedicated pod hotels, tons of filter media, macros, and lots of coral.

Any ideas for a little buddy to add?

Thanks!
