About, my sand sifting starfish. I put them in only after the tank had started building up alge and junk on top of the sand bed. I had heard that they could starve and was conserned that would happen. It was a new tank, and I'm new at this and I didn't want to start out killing things. I was told that with sandsifters if they start crawling the walls alot more than normal they are hungry and looking for food, (sandsifting stars don't climb walls very much at all). They have done this one time, about a month ago. So, I didn't clean the tank for a day or two and they went right back down in the sand. I now leave things down close to the sand bed a little dirty, and they now seem to be busy, happy and keeping the bed beautiful.
I do think I might have to take them out sometime, I'm wanting to have some jawfish and I have been told that they might not co-habitate well. I really like the starfish but don't want to have a gang fight on the sandbed.
