I recently set up a 65g tank (freshwater) I recently noticed there is a "oily" look to the top of the water. Before I purchased fish I took a sample of the water to the fish store and they said it was fine. I then purchased 2 angel fish, 2 parrot fish. Now about a week later I just added, 2 silver dollars, 3 silver tipped sharks, and 3 goldfish. Now we noticed the oily look to the water. Any suggestions would be nice the fish seem to be very active and healty.

I've noticed the same thing if I don't change my water for a long time (more than two weeks). How long has your tank been set up?
A water change always fixes that for me. You can probably also try an activated carbon filter because it will remove dissolved organics that may be causing that.

this isnt related to your question but you probably shouldnt have gold fish in with tropical fish they like much cooler water like 60's while tropicals like 70's either way you have your tropicals are getting freaked out cuase of cold water or your golds are getting freaked cuse of hot water i would suggest doing more reaserch on the subject of golfish and tropicals because i am not an expert (p.s lfs people do not always know what there talking about most of them just want to sell you stuff)
The tank has been running a little over a week. Fish in less then a week.
The water temp is between 72-74 and all the fish seem to be happy.
I will try to change the water asap. Hopefully that helps.

more surface agitation and carbon. water changes never hurt and i would suggest 50% at least weekly for any tank.
parrots can get big and may be too aggressive for the angels. the silver dollars should be fine with either but are more appropriate with the parrots. im not sure which silver tipped shark you have, but the columbian silver tipped shark is actually brackish and usually dies after a few months of being kept in pure freshwater, and adding salt wouldnt be good for the other tropical fish. the goldfish need to go. keep testing your ammonia and nitrites until both go back down to 0 after they spike. until then you may want to slow down (or better yet, stop adding fish).

Still not to sure what it was but the water is crystal clear now and the fish are still doing fine.
hey there, i take it that the tank may not yet be cycled so please always monitor your ammonia and nitrite levels... if they shoot up, do emergency water changes... (i guess this is no longer related to the original question)
and i second the fact that you are better off without mixing tropicals and coldwater fish.. no problems now but you might encounter some major problems in the future
good luck with the hobby

Sad thing is I (being new to the hobby) told 2 people at the LFS that I didnt think the gold fish were good for my set up. They both told me there would be no problems. For there stupidity ( I guess mine to for not doing more research/ not finding this site sooner) I will no longer buy from them.
it's cool the LFS will probably tell you the internet geeks are all idiots and they've been doing it for ever. I used to believe them until I realized they have an economic incentive to sell you whatever you want because they work on such small margins. Once your fish get sick they'll start to sell you medicine too.. :coffee2:
