not bashing u, but couldnt that be more so from over feeding them? Kinda gotta think of them as humans, there are healthier food choices to help the system move smoothly, like spirulina or veges
oscars are insectivores for the most part, feeding on all sorts of invertebrates that hit the water surface as well as other things like nuts and seeds, etc.
this is not to say that they wont eat of the occasional fish.
and no i am not the least bit offended, i 100% agree with you!
constipation is actually not a problem for my O's thus far....but a quick visit to any of the oscar sites out there will give you an idea of just how common this is...
you would be hard pressed to find someone who feeds a more varied diet than i do:
hikari cichlid bio-gold (soaked in vitamins once weekly)
tetra cichlid sticks
crickets
earthworms
krill
panfish worms
occasional fresh/frozen fish filets
feeding a varied diet is important for most cichlids, especially oscars which are prone to HITH when diet is poor and nitrates are high for prolonged periods of time.
i think that feeing oscars (and probably other omnivorous cichlids) foods which are high in fats too often is probably responsible for constipation in most cases.
i feed several times daily, but very small feedings at each interval.
i am also anal about water quality with my oscars.....i usually do 25-30% water changes 2 times a week, sometimes more.
