I feed my salt water fish 1 frozen fish cube a day. I let it break up and thaw in a cup of water before I give it to them. I am pretty sure that everyone gets enough to eat but I am a little concerned that my orange spotted goby and scooter blenny may not be getting enough. They do come out when I put the frozen food in there but I am just worried that its just not enough that they are getting. I have always had freshwater and am still pretty new to the salt water fish world. It was always easy with my feshwater because I could always just drop some sinking food or algae wafers in there for my bottom feeders. Is there anything like that for salt water fish? Can anyone tell me what I should buy to feed them?

Thanks
