Wow now I know what they mean by spike on the front dorsal if that is a real pic..geez.
I had one before from here that was a larger one and I just could never get him to eat. He never had good color and after a month in the DT I felt so bad for him I wanted to put him to sleep.
I spent over $100 in pods to give him plenty to eat and have 200 lbs of live rock that had been in a tank for 8 yrs and then mine for a year. But I lost him.
I would like this one to start eating other things as well so I have been trying to feed mysis, brine shrimp and arcti pod.
