HI there! I've been searching the Internet trying to find some answers but it seems like things never got answers. So I got a betta over a month ago and he has a 2.5 gallon tank that he really loves. I know it's a little small but I clean it twice a week and he seems super happy to go into the other area well I'm cleaning the tank. He never seems stressed and he always putting on a show in the water-plus (and I'm probably just crazy) I feel like he can hear me and maybe understands? Like I say his name in the morning and he always comes out and just gets super happy. Anyway, I got three little hornel snails to company him in the cage, they said to put one algae wafer in a week. That was fine at first but recently the last three times they've spored. They look like fuzzy white stuff growing out from it, and the first time it happened there was about four clusters(the pellet was in the back and I didn't see it until cleaning day. So it still grew really fast.) this is my first fish that wasn't a family fish. However we probably had hundreds of fish growing up and I've follow the way my mom raised fish pretty much to a T. Until I got the snails I had no problems. After the second time I broke the wafer into pieces and used maybe 1/3, maybe less a little less than 1/2 tbh. But it still did that. I'm wondering if my snails aren't eating so it's molding? But how are they alive if they aren't eating that? We had snails when I was a kid but they were just random like river snails and tbh we never fed them. We just had a lot of fish that pooped and that kept them fed lol. And they flourished. We had new snails all the time. Anyways, thank you for any help.
