Can Goldfish survive in tropical water?
If your water temperatures exceed 68 degrees, your gold fish will survive for a while but will be in poor health. They can remain in a warmer water 70 for a short time with lots of dissolved Oxygen. DO2 can only enter the water by means of water touching air, filter, waterfalls, wind, waves, fountain powerheads etc. Really, gold fish should remain in an unheated tank. Ponds which get the summer sun are different since there is pleanty of moving water and they are deep. here are a few fish that can go with your goldfish: The most common coldwater fish is the goldfish, followed closely by it’s larger counterpart, the Koi. However there are many other interesting fish that do not require a heated tank. Many coldwater fish are large enough that are only suitable for ponds. However, can be kept in adaquate aquariums. Barbs – Several readily available species of Barbs are tolerant of temperatures into the mid sixties, or even lower. All are easy to care for, and are suitable for a community
The definitive answer is, ‘yes’. Goldfish, in many different varieties thrive in the tropics. But like any fish, you should introduce them to any change in temperature SLOWLY, and be careful how high you set your thermostat. Even (most) tropical fishes do not like water that’s too hot. Start off low, and increase the temperature every 2-3 days by one degree. The common goldfish is a fish bred from the carp and any one who has lived or been out in the tropics will tell you that carps (including goldfish and koi) live and thrive out there. I have seen them in mixed tanks with angel fish, zebras, gouramis, etc., – all tropical fish.
