Hi Guys, I'm after some advise on how to stock my nano tank. I wanted to put a coral on the rock at the back right but not sure what to go for. It's a relatively low flow zone so something that doesn't need to much flow or light. Also would you put another fish in a tank that size, I put a firefish in a few months ago and he died after just a few days, was possibly bullied by the gramma. The rock where I'd like a new coral to go has a tunnel through it, I was hoping it would live in there but he avoided it.
I keep the dkh at around 10 and salinity 1.026. Phosphates around .03 and nitrates around .2
