So I recently added a single zebra dartfish to my 32 gallon biocube. This brings my fish load to just that and a pair of clowns so far. I know with a 32 gallon tank I am very limited to how many as well as what kind of fish I can add. It is for this reason why I only got one because I still have other fish I hope to add and know I realistically only have space for 3 more at max. I am just curious if anyone has experience with keeping only one of these in a tank because I know they are usually kept in pairs or groups. Should I expect any differences in behavior or anything like that?
