hey guys...if you have a school of congos or something similar (go figure)...I suggest you try feeding a large fat moth and see a spectacle of Ferocious, brutal feeding behaviour, the whole school went literally nuts ripping at the moth eventually playing tug a war at different ends and ripping the moth into different pieces, they all chased each other for rations like they haven't eaten for weeks!..when its insides opened up...all the other little fishes dined in on the contents (sorry for the graphic description)...BUT it was quite a sight and definitly gave them a moment to express their 'wild' appetite..for entertainment value as the dilma add quotes "Do try it"
