at last added 2 fire goby and no fighting
I think basically fire goby and two spot are two different type... at least they look different will prevent them from fighting.
ya two spot not easy to keep.. but luckily this one quite comfortable in my tank maybe got lotsa space to hide...especially under the big prata and squamosa!
most importantly no threat from my crazy ex-yellow tang
But I find this two spot a VERY good fish... really clean up the sand bed n no sand throwing.... worth keeping, highly recommended.
