It's a case by case deal. Mixing different types of clowns is usually a
receipt for disaster. If you put in a second clown of the same type make
sure that there is a size difference. The large will become the female and
the small the male (usually). You will want to watch them pretty close for
the first 2-3 days. If the larger fish prods the smaller and then the
smaller one shakes it's generally a GOOD thing. This would be a sign of
pairing. As far as the lights go 12-12 is a good cycle. If you are just
planning on a fish only tank the light time isn't all that important. It's
more for your benefit than theirs. If you go with Anemone and corals then
the cycles become more important.

I thought that if you mixed clowns not at the same time there is a very
good
chance they will fight til one is dead.

Les,

Set it up for the full 12. Most fish need the light as much as we do.

-Do you have any live rock in your tank? I know you said FO, but you
never
know.
-Are your lights NO, VHO, or PC?

PS,
Get another little clown for the lonely little clown in that big 80g
tank.
That way you'll have a matched set AND a mated pair. (Did you know all
clowns are born male?)

Hi All,

I know its been discussed before for corals, I believe 12 hours is
recommended, but what about FO. I'm waiting for tank to mature before
I
add
corals. I have one small Pec Clown. 80g tank 4 x 55W white (7.1K) and
1
x
42w actinic.

Its fairly dark during the day here in Scotland at this time of year
so
not
much natural light gets in. Should I just have the lights on in the
evening
for my families benefit or is it better still to have on fort he 12
hours
the fish would get on a reef? I plan to switch on/off in sequence to
emulate
it getting lighter and darker.

Thanks
Les
