i use filtered sea water, and i do a 25% water change every other day if not daily, the protien skimmer/filter that we use can handle a tank 2-3 times the ours. our water should be ok. i'll ask my husband to pick up a test kit on his way home from work. he thinks that it's dead. he said he'd look at it when he gets home. i just don't understand, it looks dead bet out of the water the tenticles are curling and wiggling around, but in the water it doesn't move, not at all, not even the tenticles, i don't see it trying to breathe. then why is it moving out of the water? i was going to flush it, but then it moved! i can't flush it if it's moving, if there's the possibility that it's alive and just taking a nap or something. although it is upside down and has been for over an hour, and it hasn't moved from the spot it was in. but if i flush it and it starts trying to swim back up, i won't be able to save it, and then i'll feel really bad. if it really is dead and has been, is it traumatic to the other bobs? will it mess up my water? how long can i leave it in there? (assuming it still tries to move when i pull it out) is it some kind of invoulentary thing? like when after you spear a tako, the tenticles stick to you and later that night the skin still changes color when you poke it? i think i might be driving myself nuts over this! what do i do? will someone please tell me what to do?!
