i bought a hippo tang yesterday and acclimated him and the let him go in my sump and he laid on his side for a while till i turned the lights on then slowly he started moving around and exploring . by the end of the night he was doing really well. this moorning i woke up and thought he was dead. he was on his side not moving. upon closer inspection he was breathing through his gills and not gulping with his mouth so i thin hes breathing ok. but even know 2 hrs later withthe lights on hes still not swimming jutst laying on his side, sometimes scoots round on his side buut not much movemetn. i know hippos do this but i didnt think it was to think extent. is he ok?? he look really healthy.beautiful colors.
