My fish is pretty pale. I've done a check on the parameters and everything is okay. Ammonia 0, Nitrate 0, Nitrate 0. It's odd that everything is reading 0... my ph is kinda on the high side since I have a cleaner shrimp. It's 8.4 about. I got the shrimp 4 days ago if this makes a difference. Aside from that, the clown is not eating and swims very low. I had the fish for about 2 month now and he had previous problems that got fixed. He was eating then randomly stopped.
