very nice cichlids. What size tank do you have? This might help you with Identification: New World Cichlid Genus Gallery
ok, that's pretty good. Oscars need quite a bit of space since they can grow to be about 13", so I was just wandering. What is the stocking in there? I'm guessing you do weekly pwcs, lol?
I have 2 pairs of Oscars, 1 pair of Green Terror, 2 Pairs of Jewel Cichlids, 2 pairs of silver sharks, and a pair of sucker mouth.
Pardon me asking, what is pwcs?
Err... I just noticed you had 2 oscars. Thats a bit much for that size tank. For one, it would be ok, but for 2 you need at least 125g tank, at least from what I've read. They get really big and are really messy.
Partial Water Change.
Here's the deal. Will all of those fish "live" in a 65 gallon fish tank, probably. But think about it this way. Place 8 babies in a 10x12 room in a house. As babies, they fit fine. They have plenty of room to crawl or do whatever else they please. Now, as they get older and become teenagers, they will start to feel cramped and as fully grown adults, if they grow fully, they will have little to no room to stretch out and move around. Is this an extreme example, maybe, but it is a very real example. Sure these fish could survive, if they don't get aggressive and kill each other, but it really makes no sense. Just because they are an animal and not human doesn't mean you should treat them any differently. Now this is my opinion and take it for what it's worth but I would reconsider your stocking. That being said, the few pictures you have of the tank look nice. Do you have any full shots of the tank?
Also, you should really keep up on your partial water changes. Weekly probably is best. Get a test kit for water parameters and see where your's are at right now. Also, never completely clean the tank. Just the filter media and then change some of the water. That is all that is needed to keep the parameters in check and not have chemical imbalances.

The fish in the 2nd shot is a Venustus or a hybrid of one, I'm sure. Totally different water parameters than all the other fish in there and I wouldn't have them together, but hey... that's just my opinion!
Yeah, at least weekly, but with that many fish your going to need to get rid of 3 of your oscars or get a much larger tank.
