One of my male seahorses (erectus and I have had him one year) is acting very strange. He has been courting his partner lately but no signs of pregnancy. Today I have woken up to him with his pouch enlarged and very erratic behaviour. He is fine when not moving and is eating but if he tries to swim (such as when i tried feeding him) he starts doing 360s on the spot extremely quickly and then realises he can't swim and lies down and eventuall brings himself upright. Apart from the large pouch he looks physically fine and all water conditions are perfecr. It's very odd, from.what I've read it could be pouch emphasymia but the spinning on the spot i have not read about, what do you think?
