Yes, as long as the gold fish is big enough not to be eaten by the catfish. Make sure the catfish is a cold water variety.
No
Yes
You do however have to be careful with your Ammonia levels if they're in a tank. Goldfish give off much higher amounts than most other fish.
The goldfish is not a member of a catfish. But they both belong to the kingdom mammalia.
Yes,Neon tetras and catfish live together well.
a catfish will eat any fish that is 3/4 its size.
No, because cats and fish don't mix. Ha.
Goldfishes and guppies should be kept in a different tank....
Cats can and will eat your fishy friends. It is always a good idea to keep fish bowls and aquariums. Fish occasionally like to jump out of their homes. Yes, catfish can and will eat goldfish, and any other fish smaller than they are.
Yes. But large catfish eat small bluegill.
other goldfish and mabey som catfish
yes
No. Goldfish are cold-water fish, plecos (which are catfish) and your other catfish are warm-water fish. You run a heater in a pleco/catfish tank, but no heater in a goldfish tank. Plecos are also territorial toward conspecifics, meaning two plecos in one tank will fight and possiibly kill each other. The other problem? A 50-gallon tank is only large enough for one pleco, even if they weren't territorial. I would return one pleco, either the catfish--what is it, a bagrid?--or the other pleco, and the goldfish. If you want to build a community around one of these big cats, try some medium-sized tough cichlids like Jack Dempseys or firemouths. I kept three Dempseys and a pleco in a 55-gallon aquarium for years, and they were great together.1st: Plecos are catfish.2nd: Goldfish can't live with any other fish besides other goldfish. 3rd: What kind of Catfish is it? 4th: 1 pleco per tank only!
No. That is a catfish.
Yep
