Ever have surface scum in your planted tank? When you throw in some tetra bits and notice the scum seem to be pushed away from the fish food?
What's happening here? Thought this is interesting if someone can help explain.

Actually, my tank has some form of surface movement due to the fan blowing... But on some days (oh, those heavy days! Haha.... !), the layer gets VERY thick! And its really slimy...
Oh, Juggler, the food repelling the scum is due to surface tension or something like that... Exact theory needs the younger engineers here to explain... Nothing to do with the scum running away from the food... The scum will be similarly driven away from anything foreign newly added to the water surface..

I'm crypt collecting... Starting cheap, now have Cryptocoryne beckettii, C.beckettii var petchii, C.crispatula var.balansae, C.griffithii(Melted! ), C.nurii, C.parva, C.pygmaea(Melted! ), C.tonkinensis(Melted! ), C.walkeri, C.wendtii 'Brown', C.wendtii 'Green', C.wendtii 'Green Gecko', C.wendtii 'Tropica' and Cryptocoryne x willisii
Oh, juggling is hard work, man!...
Actually it happened in two of the three low-tech (low light, non CO2 ,no fert, no water change, no filter) tanks. All are without those scum eating fish such as mollies or swordtails.Originally Posted by PeterGwee
Interestingly, one of the three tanks doesn't have this problem. I suspect the big ramshorn snails sometimes swimming upside down at the water surface have consumed the scum.

So confirmed Swordtails do eat the scum/protein layer? The surface skimmer can be a real hassle sometimes... And it doesn't really work very well!...Originally Posted by juggler
But nowadays VERY difficult to get good and nice swordtails...

If you use the skimmer that looks like the brand Tom (if i'm not wrong) than you won't have any problems. But if you use the eheim or the atman type than you're likely to get very frustrated.
