OK OK camera #2 died whitewater rafting. Camera #1 got stomped by a Bighorn Sheep I was photographing. So I will post pics as soon as I get my mitts on another digital. Here it goes:
Nylon Mesh Material, like a football jersey. Washed and soaked in aquarium stuff (stresscoated/zymed water) just in case. Net goes over top of tank, under lid so he can't cut himself playing tigger, he coils at the bottom and shoots straight up. The net is stayed yes! like a reverse circus net, the attachments go down the sides of the tank and I put bungee stretch cord and secured it just like a boat to a dock, same hook style same fig. 8 wrap for quick release and retying. (The cats like this part)
Materials intended for commercial fishing weren't so fish friendly , I just started there cause I hail from a commercial crab fishing town. Those nets, even shrimp net could cut a fish. If you could get a big enough piece of pond/koi net material it might be better. I imagine the material will weaken rapidly because it's moist (i'll let you know) I was very careful to try and make sure there's no way he can get caught in the net. So far, it's ok, can feed thru it, have to undo it to work in the tank.
This is an experiment and I think a cool idea but everyone please be careful if you try this because I don't want to hear stories of "my aro got caught in the net and died!" It's still new so please PROCEED AT YOUR OWN RISK and if anyone else had better ideas, lets hear it!!
