Help! I brought home my pygmy waspfish a couple hours ago, acclimated him, and put him into the tank where he ran around a bit at first, and then laid down in the corner and half way buried himself in the sand. I work at the lfs he’s from and I’ve been target feeding him and building trust for months. I’ve never seen him do this. The Ammonia Nitrites and Nitrates are all at zero and there’s plenty of rock shelves for him to hide under, so I don’t get why he’s doing this. When I got up close to him he picked his head up a bit, and I can also tell that he’s breathing, but I don’t know what to do. If anyone has any idea why this is happening, or if he’s sick, or stressed, or what, please help me because I’m panicking!
