can i keep a goldfish with a small crab in my fish tank?

Question

i want to know if i can put my new goldfish with a small crab.

Answer 1

There are very few species of truly aquatic, truly freshwater crabs. Most "freshwater" crabs are actually from brackish water, and are slowly being killed in freshwater. Avoid the crab for that reason, as well as the fact that it may go after the Goldfish's fins, and, the Goldfish should easily reach a size at which it would have no problem eating the crab.

As others have said, Goldfish get quite large (Commons will reach 1.5+ feet and Fancies will reach 8+ inches), so large tanks are needed. For a Fancy Goldfish, nothing less than a 15 gallon tank is acceptable, and Commons really need a pond, but a 75 gallon tank is adequate. Email me if you have any questions.

Answer 2

No. There are issues either way. The crab may grab at the goldfish fins and the goldfish may eat the crab. But, more importantly, I'm going to bet that this crab isn't in a 10 gallon tank. And if you don't have a 10 gallon tank, you shouldn't have a goldfish in the first place. So, go buy a 10 gallon tank and keep your goldfish in there, separate from your crab and in a good sized tank.

Answer 3

if the fish goes near the crab, im sure it will pinch it. if it's a fantail goldfish, i wouldnt recommend it.
