Hi, I'm new to this forum. Need some help in determining what this is floating in my tank. I have had my tank since July '09. I have 2 comet goldfish, 2 giant danios, and 2 African clawed frogs in a 30 gal tank. We just saw this big white "mass" floating around. It looked like a big cobweb, only definitely fish-related. I know my 2 frogs are males, and I am pretty sure my danios are also males. However, I am unsure of the goldfish. What would the white stuff be? I am guessing it's from a male goldfish, but idk. I couldn't find any good pics or videos online showing what it would look like. I tried taking pictures, but they kept coming out very dark or blurry, and the video was just as bad. Do fish sometimes do that when the water is a little warmer even without a female in the tank with them? I did just change the water a couple hours ago, if that makes any difference.
Thanks for your help!
