Thinking about getting a goby to add in the next month or three. I've been looking through liveaquaria and such and found a dracula goby, has anyone heard of these of these guys? Also been searching forums and found the hi-fin goby to be a cousin of the dracula? Again, anyone with experience? Anyone know of any unique looking gobies? Thought about a mandarin, but I don't know if I have enough pods to sustain them.
