Now that is strange and funny at the same time. I do agree with you about all the things that go on in the tank to keep you interested. It's more interesting than the tv set by far, that's for sure! Having your turbo's and a few hermits going after the Nori you had in your clip, that's a new one. I haven't had that happen yet! Maybe your tank is to clean and they're taking what they can get! Hardly... hehehe...they can find something always, but that stuff must be tasty! Great pictures!
