BTA Split

So i was lying in bed this moring/afternoon and as soon as my tank light turned on i turn to see my BTA has split! First off i was amazed then i realised my poor gonipora got knocked off its pearch and he isn't looking too good, don't know if he will make it but still has green polyps so im hoping for the best.



You can see my BTA isn't looking too crash hot, i know part of being away for a 5 week holiday and lack of time has meant for some poor husbandry but i've got water mixing up for a big water change. Should i be hand feeding these guys since they have reduced in size now with some pieces of prawn? (shrimp)



Thanks
