That's very interesting, I like the look of it painted onto a rock. A bit too much work for me I think and I am WAY too cautious these days as it has taken years to get to where I am. guess to sum it up is that you use egg white as a sort of 'glue' (and goodness of coarse), similar to cooking (I believe, no experience of that either)? I imagine (as with everything else) it is much easier to get what you need (ingredients etc) in large countries like USA and Australia than here in UK! I guess you could also do this to make your own shrimp lollies as well if you have the sticks?
It is sunday so treated my Taiwan Bees to a shrimp lolly and some spinach leaves so they are very happy, though squabbling over everything.
When I use the Bacter AE which is powder I put a bit in the tank and the shrimp swim to the top of the tank to get at it before I have even had enough time to stir it in to get it to sink. Makes it difficult then to stir it in without bashing the greedy shrimps?
