A buddy of mine offered me a yellow sea apple for my 100 rubbermaid fuge/lookdown and want to get some more info before I agree to take it. He is feeding it rods foods with a tukey baster and it is eating well. The other inhabitants it will be with are 2 serpent stars, spawning pair of clowns, pencil urchin, shortspine urchin, large sally lightfoot. My biggest concern is the toxcicity. I have head that it is not as big of an issue as it once was due to the equipment now a days. Will a skimmer really pull these toxins out? I am running an ASM g4xx on a 250g system. I also use about 2 cups of cabon changed monthly.
