I found a cuttlefish egg at my LFS a couple of weeks ago, and after doing a little research, I decided I was up for it and I bought it. It's hatched since and is 10 days old today. I have some questions, but first, my tank stats: Salinity - 1.025 Temp - 78-79 degrees pH - 8.3 Ammonia - 0 Nitrite - 0 Nitrate - 0 First of all, I am not exactly sure on what species it is. The egg he hatched from was small, round and black. He is very small, though in the last ten days his growth has been obvious (IMO). His colors can range from sandy colors to reds and purples sometimes. I have mysis shrimp on order, but so far he is the sole resident of a reef tank I have had for quite a while. So, questions: Based on the color and shape of the egg, any idea what it could be? Im hoping its a bandensis... I did not keep him in a breeder, he roams around the tank freely (a 30 gal biocube. i modified the filter intake parts so that he would not get caught in them). I have seen him chase stuff around, it seems like he has been eating pods. I am concerned tho, because he doesnt seem to eat that much, also, he tends to stay in one place a lot during the day and doesnt move much. At night, when the lights are off, he comes out a little but again, he tends to keep to one area of the tank per night. Is it normal for him to be fairly shy? Should I be concerned?
