So I have a 13g wide with two live plants, 5 neon tetras, a Japanese bamboo algae shrimp and a betta. I just recently got the betta and added him to the tank- he's doing fine with the others, I've had no problems with him. When I got him, the shop owner gave me a sample of Repashy super-food Shrimp Souffle because I was interested in the concept and he's just a nice guy! But anyways, I got home and made some of it and put some in there, and more when the piece was gone(I started with small pieces) and since then, it probably been 4-5 days, I've noticed small flowing things on the front glass of my tank! Someone said it sounded like Hydra so I looked it up and it does kind of look like hydra, BUT they are soooo small and there's TONS of them! My water is kind of cloudy too. I think it's because of the new food but not sure anymore as I read that hydra can be eliminated by adding salt to the water which I hadn't done my last two water changes. My betta really likes the repashy food so I want to keep feeding it, and my neons are starting to like it also. But what can I do about the things on the glass? The cloudy water? I just changed my filter cartridge today as I noticed the cloudy water and I checked it and it was super dirty and plugged up. Help please?! Thanks!
