How Soon Before You Can Tell The Colour A Cherry Shrimp Will Be?

That's what I've done. I have bits of moss still caught under the cotton but most if it is sitting on the bottom of the tank. I've tried tying it back on with a second length of thread over the first but the bits still won't stay put 

Next time I do a water change on the 50 litre, I'll keep all the lose bits of moss to one side and see if I can tie them on any better. Maybe have the spiral turns closer together and see if that helps. If not, I'll be back with photos.

The problem with that is the moss is lots of 2 inch long strands so it would need rather a lot of glue 

The main problem with superglue is that I'm notoriously clumsy. Last time I used it I managed to get some on the worktop despite putting down paper to catch and absorb it. My husband was not at all happy about that. And how I've managed not to glue bits of me to things is something I've never understood

Haha you too?

I've lost count of the number of times I've glued myself to things or other parts of myself.

Mind you, the fact that it's so effective at gluing skin to skin has proven very useful in the past, when as it was used to close battlefield wounds during the Vietnam conflict.
