Do TSN hunt at night or during the day...or both. Sadly my TSN refused his prawn tonight which upset me. I even poked him in the face with it and he didnt move...he also looked suspiciously fat. I think he has taken one of my convicts. I want to design the tank with two big piles of flowerpots and drain pipe at each end of the pond, with the idea being that at least two pairs of cons will survive and breed giving a constant supply of food. If TSN hunt in the day, I need larger caves the cons can race round to lose the TSN, but if they hunt at night I need caves the TSN cant fit in, the flower pots will be death traps. I hope I can get it to work!
