Last night i went to say goodnight to Honey and Spot ( Bettas for those who don't read
betta bits) and there was Spot chasing a very fine wriggling worm!! He doesn't have a tank with a light sadly but after my first shock i noticed many worms in there and i freaked!!! I did a big hoover/
water change as the pc booted up. Got online and Fishlore forum was down. Well i was in a panic as Spot ate one of them.
I did a net search and first one was this sitehttp://www.aquariumfish.net/information/having_trouble_p2.htm
after reading it i calmed down. I read other sites about Planaria too. It's not an issue that comes up so how many of us know what happens in our tanks after dark!!??
