Wow thanks everyone, will definately take your advice over the Prime, I hadn't even heard of it before.
As for the advice about the rams - came home from work yesterday and the larger one was dead. The other one seems ok and has stopped guarding the area now its on its own.
Any advice on fish death causes? It seems like every time I add new fish to the tank that I have a fatality and there doesn't seem to be any reason for it that I can see. I have got testing kits and my
lfs always test the water before they sell me fish but its most upsetting to keep losing fish. Especially now its one of my rams after 3 days when they just seemed to be so well settled.
