For many months now, they have been closed on Mon/Tue and had hours of approximately 5 to 8pm on Wed/Thu/Fri with the shop being open for a full day on Saturday and Sunday.
Lately though, the shop is going through a rough time. I was in there last month and most of their tanks were broken down or empty and they had very little live stock on hand. The girl working there mentioned they were preparing to make some changes with perhaps a full time manager being hired to help out.
I drove by this past Sunday in the middle of the afternoon and they weren't open though. That didn't seem like a positive sign to me.
I have a friend that knows one of the owners. I'll ask to see if I can find out anything definite.
