Thanks Steve, hope he began to be more sociable soon...
Juan Pablo, I guess he is all right, but I´m beginning to worry. Lots of contradictory information on the web. They say that it is carnivore, others say that he feeds on live fauna at the sand bed mostly on copepods. If he feeds on copepods I guess that it is trouble, my tank has only like 6 months old and already had a mandarin that died because on lack of copepods. In other places it says that it is just like the diamond goby which is also described as easy to keep. Any advice, I´m worry about my tank´s size but I have a refugium which seem to be full of worms and fauna. Any advice…
