New fish fail

Hello. I bought a 5.5 gallon top fin tank for my son’s new glofish. There are only 2 of them. It says it’s a complete beginners set.

the fish have died within a few hours. I followed all of the directions for set up.. they are tropical so I bought a heater too. Keeps it at 78.
I’m wondering if you need an air pump too? I thought the water filter thing did that...

probably set it up too fast.

and it would be advisable to get a much larger tank. 10-20g for instance.

You can also read the techniques in the link in my signature. Just my way of setting up a nidw balanced stable system.

All if which is worth at most .02

maintain Fw and marine system with a strong emphasis on balanced, stabilized system that as much as possible are self substaning.

have maintained FW systems for up to 9 years with descendants from original fish and marine aquariums for up to 8 years.

With no water changes, untreated tap water, inexpensive lighting by first starting the tank with live plants (FW) or macro algae( marine)

Hello Heather...

You might read up on the "Nitrogen Cycle" before getting any more fish. When it comes to keeping fish, a larger tank is preferable to a small one. i started with a 30 gallon and it was more forgiving of my mistakes. Also, a very hardy fish like a Comet would be a better starter fish. These are cool water fish and don't need a heater. Keep us informed and we can help you.

Are you making sure the surface tension of your water is breaking?

Breaking the surface tension (splashing the water on the surface) allows oxygen to enter back into the water for the fish to "breath." One way you can do this is to set your filter up so the top nozzle (the part that pushes water back into the tank) is positioned right on the surface. This will constantly stir up the water, allowing oxygen to enter.

Considering the small size of your tank, I don't think you would need to stir up the water that much.

It also depends on what kind of water you are using to fill the tank. If you are using tap water, there might be a chance that it contains harmful chemicals like chlorine. To fix this, you can buy tap water conditioner, which eliminates the harmful chemicals. After you treat your water, give it some time to filter through your tank. It usually takes about a day before it is safe to add fish.
