The easiest to keep fish are generally hardy omnivores; the easiest of these are the clownfish and damsels. Beyond that, easier species include the sixline wrasse, royal gramma, bangaii cardinals, coral beauty angel, large thalassoma wrasses, many of the larger angels, lionfish, groupers, and triggerfish also usually do quite well if provided with ample space.
I know this is almost 10 years old, but I signed up just to make sure that whoever gets here from Google is absolutely clear that you should NEVER put your betta fish in saltwater. They are Freshwater Fish, hailing from rice paddies and rivers in Thailand and other Asian countries.
And even if they were Saltwater Fish, I wouldn't place them with hermit crabs, who would have a field day cutting your betta fish in half the moment the betta tried to pull its "This is my land" shtick and attacked at the hermie.
a betta i think and a hermit crab
A saltwater fish tank can be half freshwater and all of the saltwater fish will live but not for very long.
uhhh.. yeh buddy
No. Bettas are freshwater fish. Seahorses are saltwater.
No. Not in the traditional definition of the tropical tank. A tropical tank is a freshwater aquarium. Regal Tangs are saltwater fish and go in a saltwater tank (marine aquarium).
It is called coraline algae.
Certain freshwater fish can survive saltwater conditions; examples are black mollies, mono's and scats. All of these fish aren't truly freshwater or saltwater, they are Brackish. Brackish is between freshwater and saltwater, and so these fish are highly adaptable.
i think you would need a medium tank for your fish.
no its not okay
no because there on fire
because when you go to the coast you need a tank for the salt water fish
No, you need a special salt for a saltwater tank.
at Petco they sell it in water bottle shaped things.
