Can goldfish eat sea lettuce?
I picked up some sea lettuce attached to stones from the local beach near where fresh water was entering the sea, and have washed off the salt water, and placed it into my fresh water tank. The leaves appear to be pearling so I guess they might survive.
The goldfish are eating it as well as evidenced by the green feces now appearing.
But could this diet hurt the goldfish?

sea lettuce might be given to goldfish but only in a small quantity,this is to avoid it going bad before it is eaten.
sea lettuce is not toxic if fresh and it contains minerals and vitamins that are good for your fish,fish that are herbivore or mulitivore will eat it(herbivore=plant eating,multivore=mixed diet plant and meat eating).
sea lettuce lives in salt water and are not able to survive in fresh water(it can survive short fluctuations in salt level but not in fresh water).
when sea lettuce breaks down it release hydrogen sulfide this is very toxic and it will kill your fish.
a truck driver was killed by the hydrogen sulfide gasses from his cargo of sea lettuce,several people and animals like horses have died after beeing poisoned by this gass,more details about this in the link.
here is a link read the ecology part en.wikipedia.org/wiki/Ulva_lactuca.
it can be hard to identify the eddible types of sea lettuce.
