what size tank, what size tankmates. what size oscar, and how often do you do waterchanges and how much water do you change each time?
P45 is right in all of his posts. You need to pass on this info for advise.
Sounds wierd that the Oscars can't handle the water change. I've had
Ocsars for years and not to mention many other species that are talked
about frequently on this site and it depends on what you get your fish "used"
to in the water change area, if you have been doing 75% changes consistently
then it's not that! I have never lost a fish to a water change. But, until you
let everyone know the tank variables, can't help.
Smellfishy -- nice tank, but to many variables and tastes in fish keeping.
Everyone does not do things the same way, what works for one, may not
for the other, depends on factors as stated previously. BUT, I GOTTA SAY
I'VE NEVER SEEN A BIG WATER CHANGE DO ANYTHING BUT HELP THE FISH!!
