Pond question

[Ifish]

Hello all I just signed up to this forum earlier today to see if you guys could potentially help me out. I'm not really new to bass fishing, but I didn't know where to post this. Anyways here is my dilemma. I just recently moved and my house is on a small pond, id say about 1.5 acre pond. I live in south Florida and my house is relatively close to the everglades so I dont think bass fishing should be much of a problem. So when i first moved in i experimented and tried some bass fishing. I didnt catch anything not even a nibble. I did see some bluegill and I caught a few of those for some bait, and caught a few catfish. I notice there is alot of catfish, but i have yet to even see a bass. I tried a few more times with vaious teqniques, but still failed to catch a bass. I gave up for a while, but eventually I just recently went to try again and I noticed that all the bluegill were gone and still no bass. Theres not a bluegill or bass in sight, I still se catfish though. Anyways I was really excited to move on a pond, but i have been very dissapointed and cant catch anything but catfish, not even bluegill anymore. What is wrong with this pond? Where did all the fish go? The pond very little structures if any, and it is connected to other ponds in the area that do have fish. I know this post is long but to whom ever took the time to read it thank you and all comments are greatly appreciated.
