Hi I recently got a comet goldfish. I won it as a prize from my school when they were having a fundraiser. I brought it home and put it in a fish bowl as I didn't have a tank to put it in and did extensive research the whole night. The next day I purchased a 10 gal tank that came with a filter, tropical fish food and a dechlorinator. I had no time to cycle the tank as I feared it would fair a lot worse in an unfiltered bowl. The following day or today Apr.15 my parents went out and returned with an oranda unaware of the fact that thinner and more slick and rounder goldfish don't exactly go well together. We were going to return it but by the time we returned to the store it would have died. They also purchased an ammonia reliver and goldfish flakes. I am now in a loss of what to do. I have a small 10 gal for two growing goldfish. I am aware that they need now a 55 gal in order to accommodate them. I have questions on how I probably treat the water as I didn't cycle and make sure they survive until I have the money to buy a bigger tank. As well as what supplies do I need to purchase until I can upgrade their tank.
