Thanks. Yeah. I should have known better.. I was impatient and made a long drive to get them. I probably made it worse by stressing them with the trip, tank changes, and meds. Hindsight... Hope I learn and grow and just maybe someone reads this a has another little scrap of experience too

I feel your pain. I'm still fairly new to fish keeping myself. Just posted this doosey. I had my own mistakes before taking the time to put together a quarantine tank and there's still these tough breaks that are so discouraging! But man when you get that planted tank going and have the patience, time, and effort to see it through it becomes really magical. A few months of work and I have the tank below finally set up. It helps offset the tough days.

Hi all, I could use some advice.. I live in Tucson, AZ and we've got a somewhat limited selection of pet stores so I thought I'd try out the store on the far side of town. I first went to look and thought the fish looked pretty good, so I came back the next week to check again and ended up getting a group of 7 Panda Corys despite a lone dead fish in the tank which obviously made me a little wary. I got home, added them to my quarantine tank, dosed with the med trio, and observed. I lost the first 2 by the next morning. I lost another later that day, 2 more the next morning, and by the 3rd morning they were all gone. Along the way I watched for signs, checked ammonia, monitored temp, and did not feed but it wasn't until the last morning that I noticed some potential gill flukes. Did I miss something here? Should I have immediately changed tactics after the first fish died? If I see a dead fish at the store is that an automatic red flag? Does this "just happen" sometimes? Is there an issue with the quarantine tank? Should I reach out to the fish store? Quarantine tank is a 10g plastic clear tote with lid and extra holes added. I have a quiet flow 10 internal filter and an air stone. The tank is ~77F with no heater during the summer because the house temp is quite steady. I keep it bare bottom with fake plants with some snails to keep a small bio load in there. I've had it going for about 3 months and have moved 2 previous groups of guppies through it that are now doing well in a display tank.

Great idea. Simple. I've probably been overthinking it! It's an Aqueon Quietflow E Internal filter https://www.aqueon.com/products/filtration-media/quietflow-e-internal-power-filters Thought it was a good quiet option in our living room but debating just changing to a sponge filter.

Looking for some tips. I'd like to add a prefilter sponge to my internal filter before I go and add some Cherry shrimps to my tank. Any ideas, suggestions, techniques? I can't think of an easy and obvious solution...
