hay there, you have made a beutiful decision. some things to take into account with sea apples is that when they die, or if they are HIGHLY iretated they will rid of there waste, which is toxic to fish, so if you plan on keeping him make sure there are no expensive fish in your tank. I have had one since i started my tank about 8 months ago, and he is beutiful. things to look for on them is that there tenticles are active. they should come out on a regular bases. also, another thing is when they are not doing good they will turn a white color. just so you know they chance there shape quite often, this is nothing to worry about. I had mine blow up to the size of a softball before, it scared the he** out of me but all was fine. as for feeding this is where the importance of this animal comes in. they should be fed atleast once a day. I fed mine brine shrimp out of a turkey baster, just put it right around the tenticles. as far as irretating them, it takes alot. mine as survived threw a cycle of a tank, a 5 pound rock falling on him, not to mention shipping from california, and i live in ohio. another good thing about them is that they don't need any special lighting. I hope I helped you atleast a little. what kind did you get, a white one with red and yellow, or a purple one with red and yellow
