firefish goby odds

[christyf5]

Hey guys,
So I have two firefish gobies (Nemateleotris magnifica). When I got them they were both fairly small and the same size. I've had them for about 7 months. When I got them they were in my 29 gallon tank all happy and they hung out together. Of course they've grown since then but one has grown quite alot more than the other and is probably about 1.5-2x the size. Since putting them in my 48G tank they were fine and hung out at one end of the tank where most of the rock is. Lately I've noticed that the smaller one hides behind the rocks alot and the big one won't let him come out. When I feed I feed mostly in the middle of the tank to distract the bigger one and then put some food over towards the corner where the little one is hiding. I don't know how well he is doing since he mostly just lays (upright) on the sandbed which I don't think is all so good for him. So what I'm wondering here is that since they are obviously not thinking about pairing up (ever). What are my options? Which do you think would be best for the little one??

Option A: Getting more live rock and spreading it throughout the tank (I'm going to do this anyway, sometime soon I hope). I'm hoping this will allow them to spread out more. Right now they hang out in about a 1 foot corner of the 4 foot tank. I guess they like to be where they can hide easily.

Option B: Find a home for one of them (I'm leaning towards keeping the little one mostly because he is cute and little and because I feel sorry for him).

So do any of you figure option A will work? For now I'm going to put the bigger one in a quarantine tank until I can get some more live rock. At least this way I can try to fatten up the other one. He isn't looking thin at all but he looks rather forlorn.
