i noticed one of my clowns was hiding this morning and the other one was erratically swimming around the tank, his face had a white tint to it, he looked stressed, hitting rocks while swimming, they never do that. i tested ammonia and it was at 1 for sure maybe a little higher, i tested ph and its normal. i dosed the tank with prime and all seems well with the fish, they no longer look stressed and are looking for food, im not gonna feed them this morning. peppermint shrimp were out , not normal. yesterday, i did a little tank cleaning, moved a bit of sand back into place after its been moved by powerheads, scraped some green corraline off side tank walls, nothing major. yesterday, i did notice that 1 zoo was bent over like it was deflated, never seen that before. all the corals, what i have anyways, all look fine, completely open. what the heck happened? do you think i stirred something bad up when i moved some sand? my sand is only an inch deep, possibbly 2.5 in spots that built up from water flow. im gonna test ammonia again when i get home from work and start doing some water changes throughout the week. im gonna try and test everything before i go to work and see if anything else is out of whack im stumped.
