You have a very nice sized, flexible tank there. Have you looked at the fish inm local pet shops so that you can tell us what kind of fish you like? Maybe if we knew, we could help you choose things that would go together well.
Hi princess
I think angels and guppies do sometimes fight a bit but nothing to bad, a good starter fish might be;
6 corys
some guppies
some mollies
some platies
and maybe 2 angelfish
and this would probably be the best order to put them in;
platies
mollies
guppies
cories
angels [if you get them, if not, some dwarf gourami could work]
John.
A lot depends on which killies it is that you like. Some are just as nice in a community tank as the guppies would be, but others are not all that friendly.
you could substitute the platies or mollies with some lampeye killifish or Aphyosemion australe or Aphyosemion striatum
So the list could be;
6 corys
6 guppies
5 mollies
3 Platies
4 lampeye killifish
and maybe 2 angelfish
or
6 corys
5 guppies
4 mollies
6 Gardneri Panchax Killifish
and maybe 2 angelfish
Hope I helped Princess,
John.
