How long will Liverock live without any fish or inverts in the tank? The reason I ask is a LFS has some seahorses FS and he has two sold already. When I asked why they didn't pick them up he said the guy had to cycle his tank. He said he has been running a tank with LR for 3 months but nothing else in there so he talked the guy into a damsel to cycle the tank. This just doesn't sound right to me. Shouldn't a tank be fine for any type of fish after running with just LR for that length of time? I know you don't want to just dump a bunch of fish in there all at once but I think 2 baby seahorses should be fine.
