So, today I implemented another part of my plan for my poly tank and introduced 6 congo tetras. Once in the tank they were a lot more skittish than I expected but I thought they would settle down after a while. An hour later they didn't seem to be settling but I put it down to them been wild caught. Neither the polys or ctenopoma seemed to be bothering them but they remained huddled in a really tight group, not swimming around exploring. I began to have some doubts as the evening wore on so I made sure I put plenty of food in. The tetras didn't eat or even look interested. As I carried on watching I saw my delhezi take a bit of a lunge at one of them. Then the ornates started hovering around while the delhezi seemed to be stalking them from the cover of the plants and driftwood :-O Enough was enough and although I was just about to go to bed I realised they were not going survive the night. So, enlisted long suffering partner to help dismantle the tank and catch them. They were actually much easier to catch than I expected (relieved to see the net I should imagine!) and once in a safe tank they immediately relaxed and started exploring like I had expected them to do in the first place. So that's a lesson learned. Hoping they might be OK with the polys once they are bigger but I will proceed with caution!
