#Fish tank for large goldfish upgrade#
If you keep tank mates with goldfish, you will need to upgrade the tank or ensure that it is large enough to provide each fish with space and that it is large enough to support the extra bioload of each fish added. If the temperature fluctuates too much, you can add a heater into the tank and set it to a temperature that is comfortable for both the goldfish and the tank mate. Since goldfish are temperate water fish and can tolerate a wide range of water temperatures, the temperature of the water should be ideal for the tank mates too. If the water chemistry between the two fish is not compatible, it can cause issues for one of the fish species. Aside from temperament, you will need to ensure that the tank mates you choose have a similar water temperature and pH requirement to goldfish. Goldfish in general are known for being one of the least aggressive pet fish, so they will do better with other tank mates that are not aggressive and do not fin nip. However, if you are up for extra maintenance and feel that you have the necessary skills to add more fish to your goldfish tank, then it can be quite a fun experience.
