Want this question answered?
No, freshwater fish must be kept in freshwater and saltwater fish must be kept in saltwater. The one exception (that I know of) in nature is salmon which migrate from where they were born (freshwater) to the ocean and then back to where they were born again to breed.
well saltwater ghost shrimp can be found ANYWHERE there is saltwater really. i dont know about freshwater ones though.
If you are buying it, the sign should say, if you caught it, you'll probably be able to figure it out pretty easily. If this didn't help, search Google images for 'freshwater mussel' and 'saltwater mussel' and see which looks most like the one you have.
no never put suckerfish with goldfish as they will suck the slimes and scales off the goldfish and kill them. as for shrimp, i dont know???
Yes they do. Striped Bass and other Saltwater species love Bloodworms. Some people say that Nightcrawlers or even earthworms are something that Saltwater fish eat. I have never tried that though. I know those worms work great for Freshwater fish. A lot of Saltwater species like Blood and Sandworms a lot.
yes the mud skipper is fresh water. I'm doing a report in fish and i need to know all about these things. I'm addictive to fish they are so cool
Well, I know of dehydration causing you to become sick if you are in the ocean too long. I believe your body tries to "dilute the ocean", and in result your body loses its freshwater content to a point to where you will become dehydrated.
They are common in both Brackish and Salt water. I do not know of a freshwater species of jellyfish although it is quite possible there are some from the Amazon Basin. There are freshwater Jelly fish which have evolved in the carribean islands. National Geographic aired a documentary on it recently.

The only rays that I know of need tropical conditions (some saltwater, some fresh, but both tropical). So the answer is No.. Since goldfish need cold water, they would not be able to co-habit.
Forever. The problem is, the water evaporates...and it doesn't take the salt with it. You need a hydrometer to test the specific gravity of your water so you know when to add more freshwater. (That sounds strange, but it's true: freshwater dilutes the saltwater so your fish don't die.)
how should i know:(
The fastes freshwater fish I know of is the bass!
