Any Goldfish-safe Crabs?

So my search has come up with nothing, but are there any crabs that are safe to keep with goldfish? My fiance is really hoping for a crab, but my research is showing he's out of luck without a separate tank. Figured I should check here before telling him it's not possible and he needs to buy another tank.

 

Panther crabs. They’re fully aquatic too.

Thanks for the suggestion! I'll look into them

 

I'm pretty sure panther crabs need temps in the low eighties, while goldfish prefer temps mid to low seventies, even into the sixties.

 

Yeah I don't think any crabs can live with goldfish sorry

 

Amano shrimp can, they look a lot like spider tbh. I have a handful with my goldfish, and seeing them scuttling around at night is reminiscent of spiders and/or crabs.

 

I’ve actually seen panthers and goldies being kept together in person. I’m surprised about the Amanos. I might try that.

 

I actually want shrimp, so I was planning to add some if there weren't any crab options.

Cool, what temp do you keep them at? What type of Goldie's? Do you have a pic of the tank? I'd really like to see it in action, that's great you have it working out.

You misunderstood me. I’m talking about someone else. I’ll try and get pictures, but it might take a while. They were together with ranchus and other fancies. But this isn’t exactly something new. Quite a few goldfish keepers do this. As far as temp is concerned, goldfish aren’t coldwater. They’re temperate. They can even live in tropical climates.

Oh, my bad. Thanks, I'd love to see it!

 

Small fancy goldfish may work with large shrimp but I wouldn't keep any singletails or adult fancies with shrimp.

Yeah, I've done lots of research on shrimp since I want some, and I figured I'd try some and see how the goldie does with them. I know they can easily turn into a snack, so I'd be watching pretty closely and not start with too many. But I want to do a shrimp tank anyway, so if there's a crab that can go in our current tank, I'd rather go that route so my fiance is happy.

I actually have mine in with a single tail, they've been fine so far. They used to hang out during the day, but since I got more they all hang out in a cave during the day and sort of swarm at night

 

I mentioned this in another thread but got no direct experience related to the question.

I would like to establish a small population of shrimp in my tank with two juvenile fantail goldfish. I wouldn't mind if Sara and Maybelle occasionally had shrimp for lunch. In fact, the whole point is to try to make the tank more interesting for the fish by establishing a self-sufficient prey population. The question is; if they had some protective shelter, like a several ½" pieces of PVC for instance, could a population of shrimp be sustained despite some predation? How many would I need to get it started? Which kind? Hadn't thought about crabs. Even worms might fill the bill but my redworms (red wigglers) would drown. Water temperature is high 70's to low 80's all year.

From what I've read, you'll want something that gives birth to minI adults rather than larvae. I haven't looked into all the different breeds, but Red Cherry Shrimp are supposed to be decent tank makes for goldies. They have minI adults and the dads are supposed to be pretty protective, which makes them more likely to survive to adulthood and become a snack. I've also looked at ghost shrimp, and they're likely to eat the young larvae themselves if they don't get eaten by other fish. They really don't have any protection. So if you're interested in something that has larvae, you'll want to have a hatching tank that you can keep the babies in until they're mature enough to keep themselves semi-safe in your main tank.

If it wasn't your thread, that's probably why you didn't get an answer, lol.
Cherry shrimp are too small, and no matter how many you start with, they will all be eaten in just a few days. Amanos work, but can't reproduce in freshwater. So I'd recommend ghost shrimp, they don't build fast colonies, but should be big enough to live. Get a big clumb of mosses for the babies, I've had a lot of luck with sußwassertang, but goldfish tend to eat it. I've had some moderate success with java moss, the main issue is the adults can still get in, and they have a tendency to eat their young :/
The primary issue with ghost shrimp is ending up with whisker shrimp instead, which are dangerous to fish. Most of the time I get more whiskers than ghosts, ghosts have two red spots on their tail and a red spot on each claw arm. They will also begin to display a very slight pattern, from a slight red to green to brown in a wild type pattern, while most whisker shrimp stay entirely clear with a slight blue tint.
At the store, they are generally colorless, so you will have to hold them a few days to a week for them to color up, then have a backup plan for the whiskers
