yeah i know of one species that can. its the black-finned shark cat. not sure of its scientific name. it is usually sold as a young specimen, when they live in fresh water. as they grow older they move into saltier and saltier water, eventually most of them move into the ocean. i have never seen them in a saltwater tank, but i have seen many of them in brackish tanks. i really dont suggest buying a freshwater fish and putting it into saltwater. to do this with the catfish you would have to put more salt into his aqurium so eventually it would have as much salt as your other tank did. once you got your specific gravitys the same and pH and everything correct you could move him to a salt tank. i dont suggest doing this though. bo

thank you for the information,
I have this tank that is directly under sunlight and need something to consume the algae.

Saltwater catfish (Plotosus lineatus) aka Coral Cats are *NOT* algae eaters - they are carnivores & will eat any other fish/shrimp small enough to fit in their mouth. As juveniles they are a schoaling fish & should probably be kept in groups but become solitary as adults. They get to 18" in the aquarium & supposedly 5-6 FEET in the wild (Though I haven't personally seen one that size). They have poisonous spines on the dorsal & anal fins.
This is NOT a fish suited to most aquariums.

I have two coral cats, They always swim together, they have gotten quite large, like about 3 inches long each. They dont bother anyone though. I dont even think they can see very well. They dont eat any algae they eat shrimp pellets or brine shrimp

if you are talking about a pleco type cat to algea there is non for saltwater. a lawnmower blenny should do some good for that tank though. they will eat algea all day. bo
