Hello all. This is my first post on this gigantically helpful site. I have a 6 gallon or so hexagon tank in my daughter's room. We put a betta in it last Saturday, and now he's very lethargic, and really only hangs in the artifical plant leaves, and doesn't swim much unless up to the top. Is it possible my undergravel filter isn't working? We are feeding him betta food once a day as directed. Temp is about 76 or so degrees. I did about a 30% water change this past Saturday. Any and all advice would be appreciated. Want to add some others soon, but not until I get this betta healthy, if he is indeed troubled. Thanks.
Chris K.
