My new container..

..looks a bit like its future inhabitant (or is it just in my eyes?) I just have to see how big my next Versicolor is. It might be that I will have to build another smaller from a nescafe box.

What do you think, is that container adequately ventilated when it has its cork pierced about 100 times?

Pierce 100 times? needle hole? or holes as big as from a hole puncher...?

I think tank looks fine but the glass looks like those that will distort the view inside...

They are 2mm holes made with hobby drill. Actually the glas won't distort the view that much.
