I just buy a 14 g biocube. i am thinking of having a pair of seahorse. However, seahoursesourse.com tell me that I need at least 20 gallon to have a pair of them. I used to have a 64 gallon and there are a hippo tang with a tomini tang that recommended in 90 gallon or more. But in my 64 gallon they are living well. Can anyone tell me your experience about seahorse in 14 gallon. I should or should not. thanks
