What's the dumbest thing you've done?

dumbest thing ive done. HA. well a week ago i got a carpenters wrasse. four days ago it died. I thought nothing of it. today i just noticed that i have a massive ich outbreak. my damsel is freaked enough that i can't get a good look at her. my foxface looks like it dipped its fins in the sugar bowl (on the body there are white spots surrounded by brown flesh... i assume that's bad). my new puffer (two days) has mild ich around its mouth and dorsal fin.

lesson of the day: QUARANTINE THE F***ING FISH!!! i thought i could skimp on it and now it's costing me and my fish.
