Backyard Aquaponics
A place to discuss aquaponics

As for clipping claws (How did I miss that discussion?)
I have done it before. Using a sharp pair of electrical-wire cutters.
They grow back COMPLETELY the next sloughing.
Which means, depending on how well you're feeding, they will need to be reclipped every 2 months or sooner.
They will need to be watched carefully, as some slough faster than others, and they don't all do it at the same time
The yabbies will let you know in no uncertain terms that they DO NOT LIKE THE PROCESS despite it being less damaging than a 1 on 1 battle.
They also remember from last month, and are no longer easy to catch by hand.
I did this years ago, and only did it twice, whilst it cuts down aggression it is simply not worth the bother imho.
Wiring claws or using shrinkwrap, would increase the difficulty of application tenfold, and I do not believe wither will work effectively if application is possible.
Breeding yabbies and keeping more than 5, I cannot imagine wanting to keep their claws clipped.

whats wrong with just providing more hides...I havent had any probs

Perhaps I should have set out my aims and intentions clearly in my post above. I thought it clear, however I would recommend against clipping
I had only 4 in my aquarium (many years ago) and there were hides, yet they were still vicious. I was also concerned for my fish. Clipping was recommended by my LFS at the time.
