1 of my clowns has become paper thin,i tried hand feeding to no help,ive noticed he dont make clicking noise when trying to eat where as he used to a few months back,and other four clowns make really loud click like tank cracking,so its like hes teath have gone!,anyway he is now 95% dead he still breaths but just lying not responding like he is suffering,i cant bare to see him like this,i want to help him on hes way but i dont know if i can,i dont want him to suffer for days until he goes.
