One of my giraffes is sick. this is the one that had white spot, it also has been harassed bythe other giraffe. its fins are tatty, hasn't moved much over the last 24 hours, isn't eating & is very weak. it isnt quite clear on the pic but it has pale patches where its dark blotches are. i don't hold much hope for it surviving but anyone know what i could be & can it affect the others?
