The gobies are looking good although I still have not seen either of them eat. They swam thru the divider and are on the same side of the tank this morning. They look more like neons than engineers, but they are bigger than the neons I have seen ... about 2" and the head shape may be a little different. They have light blue stripes that go the length of their bodies and the smaller one hangs vertically on a fake plant or sits on top of the power head while the bigger one prefers a hole in one of the rocks. They have another 10 days left in quarantine and I have tried feeding brine, mysis, enriched brine, and some power mix .... any thoughts?

Larry - you are welcome to the tank if you can pick it up soon (the next 3 or 4 days?) I measured it again and the middle and right side are 1/8" wider than the left side. I would worry about flooding --- and yes Matt I think it is the same thickness as a 20L.

I will try to get my digital camera charged and see if I can get a picture of one of the gobies.
