>>1777244Honestly it was probably the water. Fish can go for a little over a week without food and survive, they don't always feed everyday in the wild. It was probably the water being dirty, ammonia build up is the quickest way to kill fish. They really can't tolerate it and chances are the fish guy kept a shitty filter or underpowered filter in your tank to keep your offices business.

P.S. if you guys ever plan on starting a tank and decide on a hang on filter, get the one by fluval not aquaclear. Aquaclear got bought out by fluval and fluval improved on their design. You can remove the specific filter layers in sections unlike the AC that requires you to take it all out, disrupting the bacteria colony in the process.
P.P.S. the pet hobby, especially the fish hobby is subject to >opinions, and fish keepers can be the most cancerous autists you'll meet. Especially discusfags holy shit.
P.P.P.S. Aqueon sucks, do not buy their filters. The only >good things they make are cheap tanks, water conditioner in a pinch, and I hear their newer clip on plant lights are good. Idr if they're the best at heaters but the fluval heaters are garbage.
