I am hoping one day that I will bump into ch when he is buying his supply of tights. Or do you pinch your mums/girlfriends?
I havent used live foods, but are you saying that you put daphnia in it in your tank, and the daphnia multiply in the bottle tights device, and also pop out to feed the fish? If they do I might have to try this. I thought they were larvae of some flea or other.
Wot bout if u made a frame and wove fishing wire 2 make a nice and safe fish mesh. Just an idea. Just gotta find sumthing that will stay uprite 4 the main frame. Like small stainless steel rods with smooth ends
