Today i bought a chocolate chip starfish. Now i soon realized this was a stupid idea so now I'm stuck with it and i cant get any corals. So I'm wondering if i could put it in a little tank like 15 gallons? If not how do i get rid of it? And one last thing could i get some help on what to feed it the cheapest thing possible would be nice as i don't have enough money to keep spending 50$ a month on food or something crazy like that.
