When the fish store chain like Petco, Petsmart get new fish they get stressed. Sometimes I ask when they got the fish. If you see dead, fish with Ich avoid buying that day and come back in about a week and check again. I had a fish that died within 5 days of getting it and I took it back to Petco to get a refund. My water was fine. They wanted the water seperate form the dead fish in the bag as they told me that the dead fish in the bag with water will foul the water for testing to make sure your water did not kill the fish. I got a refund this time but next time I need to bring the water seperate. They have a 15 day return policy for dead fish. I have also returned fish that did not get along with my other fish for a refund with no problem.
I'm so sorry about your fish. If you go out and buy a small hospital tank make sure it is big enough to house your bigger fish if they get sick. I bought a 2.5 gal. but switched it out for a 5 gal. as I have 1 large angelfish that is over 6" big and if it got sick the 2.5 gal would be to small. When the hospital tank in not used I house live plants and dwarf shrimps in it or you can put Mystery snails in it as they are easy to remove when you have to treat the water with medicine over taking out all the dwarf shrimps, Keep a few small fish in it til you have to use it to keep the bio going in the tank.
Check craigslist for your hospital tank. I bought one on craigslist for $10 5 gal. hex and it had everything included except the heater. You can get a cheap heater at Walmart for under $7 for a 2-5 gal. tank.
I use stresscoat in the tank with new fish also you can use Pimafix,Melafixm in case they do get sick in the hospital tank that medicine is safe for snails, dwarf shrimps,plants. I use them together. I would keep the fish in the hospital tank for 1 1/2-2 weeks and if all goes well put them in the main tank.
I'm not sure what size tank you have but I have a 55 gal. and invested in a Submariner Uv Sterilizer/Clarifier. I got it from drsfostersmith.com for $74.99 for a 5W. It's for up to 40 gal. the next size was 9W and was for a 100 gal. It prevents disease causing microorganisms. My fish in that tank are so healthy and the water is clear, I just wish they made them for smaller tanks like 20, 10, 5 gal. tanks.
