So I bought an angel about 2 weeks ago, and it's acting sickly. He's not eating very much, not responding when I put my finger right next to him, and not swimming very much. He doesn't look sick besides those symptoms though. Can't see any indications of it having a parasite. I'll post a picture of him. Here’s a picture Anyone? It's hiding in the corner. I just did a 40% water change and it perked up a little, and then went right back to hiding.
