Can sucker fish live in cold water?

Answer 1

That would depend on which kind of "sucker fish" you have. Goldfish are cold water fish that produce large quantities of ammonia, which kills most freshwater algae eaters. The tropical Plecostomus, however, has been known to survive in both koi ponds and goldfish tanks.

Answer 2

Yes they do, I had two sucker fish in my tank with my goldfish and they would attach on the sides of my goldfish and start eating them. Your not supposed to have sucker fish with your goldfish. As I have found out for myself.

Answer 3

It depends on the species. Most available in pet stores are tropical species like the plecostomus, so unless you keep your room temperature at 75-80 degrees, you need a heater.

Most cold water species also require a current to help oxygenate the water. The temperature for them should be 65F or below. Hillstream loaches are one example.

Answer 4

Theyre called skumsuckers or bottom feeders. Most of these can be found at petsmart or similar retailers

Answer 5

Small sucker fish less than 3 inches cannot live in cold water, they will die soon. But big sucker fish more than 3 inch can live.

Its better to have a heater in your tank.

Answer 6

If you are refering to the Chinese Algae Eater sucker, best not to put them in with goldfish as they might eat the slime from the Goldies body and cause scale loss and ulcers.
