I have a 38g Nuvo that's been up for a couple of months now. I have a tail-spot blenny and a Randall's goby. I'm thinking about adding another small fish to the mix. I leaning towards a fire fish but wanted see if anhone on MAAST had any suggestions. I want something that fits in the tank, is not aggressive, is colorful and is active. I figure that a fire fish fits the bill but I thought I would check.
