Hi! I am a beginning Betta keeper. I have a halfmoon male betta whom is for now, being kept in a one gallon unfiltered bowl. There is a thick film on the water top. So bad it can be difficult for him too grab his food from the surface. I have never seen this before, I have kept Betta in the past as well as some guppies and african dwarf frogs. Can anyone help me? The water conditioner I am using was frozen over the winter and I thawed it before putting it in the tank. Could this be the problem? Maybe I need to purchase a new conditioner? I break up the film every two days and scoop it out with a net. It's slimy and a snot like consistency. Can also take some pictures if that will help. He acts happy and swims around and eats just fine. I Thank you so much for your help!
