Feeder Goldfish are usually much, much cheaper.

Ask for them at any pet store.

Depending on their supply, you could get several for a dollar.

Please reconsider getting a tank for them.

The price between the bowls and tanks is very small.

If you put them in bowls, most likely none will survive

your 10-week period. Those are my 2 biggest tips for you.

If you would like care tips, you can email me.

No Problemo.

Fish tips: First thing, do not over-feed them they do not know when they are full and will eat till they die.

2nd: you will have to get some kind of air pump or plant ( your choice) to put in the tank to keep oxygen in there. If you don’t the fish will suffocate. I believe an air pump would work better because you could use 1 on all of them and use it on each one at different times of the day.

3rd: when you first get your fish, don’t just dump them in the water. When they are in the bag still put them in the water. The temperature of the water around the fish will become the same as in the bowl. If you don’t do this the fish will die of shock

4th: Every 4 weeks you need to change out the fish’s water. Put them in bags while you change the water. DO NOT USE TAP WATER the chlorine will kill them if you do use tap water let it sit out in an uncovered container for 2 days then it will be safe for the fish. When putting the fish back in the water treat them just like you did when you got them ( see the 3rd thing) If possible use distilled water

Hope I helped!
