Aquarium Advice Regular
I added a 3 inch sand sifting goby 3 days ago, and up until yesterday, I had not noticed the goby was doing much with the substrate. I came home lastnight, and noticed that almost the entire substrate had been disturbed. I mean all of it except for a small area. Last night, I watched the goby, and he just never stops... Is this normal, or is there not enough algae in the substrate and that is why he is eating so much...
Also is it normal for a goby to hit his mouth on the live rock after he has been eating? I have noticed he will eat for a while, then go over to the live rock and hit is face on the rock a few times. It seems that he is loosening substrate that is trapped in his gills. Is this normal as well?
