My local fish store had Honey Gouramis. I did research, and two weeks later, I bought some. They started laying on their side. My tank is cycled, and everything else in their is doing great. Those two Gouramis died. So I decided to get some more. They are now doing the same thing. What I have in my tank: Guppies Honey Gouramis I researched and one forum said it might be swim bladder. I've never had to deal with swim bladder though. I just thought one of them was dead. I got the net, looked back over, and he was swimming around again. He was sitting there all night, too. These things are hardy. Thanks for the responses, everyone! This morning he seems to be doing fine still. I'll definitely get the kit when I can, but I currently don't have the money (if it was 10$ I could swing it, I accidentally purchased these stupid test strips instead so my budget for testing was spent). Until then I'll use prime, thanks! I read Prime is better then Tetra AquaSafe, but since I already combined 10 gallons with the AquaSafe, isn't it too late for Prime? Never heard of it I'll check it out, it seems like a good option until I can get the API. Thanks for the kind words. Did you wind up making the same mistake I did or did you catch it before you added fish? If you messed up like me, did it work out okay?
