I recently got a betta fish for the first time (about a month ago). His name is Gerard. He has generally been a happy little guy- eating a lot, building bubble nests, swimming all over the place. Now he just sits in one corner a lot, doesn't seem to like the food I've been giving him, and is losing his bright color.
I really don't know what's up.
I clean his bowl every few days and mostly just use the stuff that makes tap water safe. I don't really use much else to put in the water. Is there anything I'm doing wrong?
Also, I'm going to try and post a pic of him (Gerard) and maybe somebody with more expertise can tell me what's going on.
