Hi, I wasn't sure whether I should post this under diseases and emergencies or habitat... but I've noticed something strange in my tank and I need some help!
I have a 10g heated tank with 1 male betta living in it. He has only been in the tank for about 9 days (before he was housed with my goldfish but it just recently came to my attention that this wasnt ideal). So now he lives on his own but this morning I noticed a white/transparent fluffy growth on two of the decorations and the gravel on one side of my tank. I have never seen anything like this before!
I've been treating him with bettafix because he had some fin and tail rot. That hasnt seemed to get any better but his attitude has changed drastically (in a good way) since I moved tanks. Just in case any of that is relevant.
Thanks for any replies, much appreciated!
