people basically feed feeders at their own risk. i dont think there is
one that is better than the other really. id also watch where i buy
them. look into the tanks, at all the fish. how many dead, or
diseased? ive heard goldfish bring out the redness in them. but
again, it makes them more aggressive. there have to be other foods
out there.

guppies ive heard have no nutritional value...i found it on a very
helpful website last night, but sadly, i forget the URL...ill try to
look for it later.

what kind of filtration do you have? these are MESSY fish. especially
when feeding them feeders. blood, scales, and other things get passed
through or just end up not being eaten at all,, soiling your tank
water.

on my tank right now, the 30, i have a magnum 350 canister filter. you
want a filter that cycles your tank about 7 times an hour. clean water
is a must with these fish. so my tanks being filter about 10.5 times
per hour. on my 125 i have a custom made bioball wet/dry filter
