So I just got two little thin bar dats not really sure what kind I'm using my phone so I can't upload any pics. Sorry well anyways these two little guys are extremely shy I haven't seen them in days I do check up on them just to make sure they are ok. But still not coming out is this normal? Or should I be worried they are about 2-3 inch and are alone in a 75 gallon tank and how well do these get with medium size frontosas?
