I would not call gbr @ quarter size a juvie but shouldnt have problem with others except maybe betta.
thanktou for your replies,still have this question thoughdoes sex of ram matter?
the betta and guppies are fine,he actually gets kinda lonely if he cannot find them the only time he will chase them is when they stick thier lil guppy butts in his face,and he only chases them a feww inches even thenThe betta and ram may or may not work out, but IMO your bigger issue will be with the betta and guppies. This combination rarely works out for any length of time.
