Are our fish ok to be together?

We have 1 kissing gourami, 1 silver tipped shark, 1 dragon goby, 1 clown knife, 1 silver molly, 1 black molly, 1 blue gourami, 1 glass fish, 1 red belly pacu and 1 more gourami all in a 80 gallon tank.
Answers:
I'm thinking you should have asked this question before you got the fish.
The Pacu is going to be a problem. They are like piranhas and aggressively eat other fish.
The gourami and glass fish need to be in groups of their own kind. You have a few different kinds of gourami, but they each need at least one other like themselves (more is better) to be happy and healthy.
I don't know about the silver tipped shark (never heard of them in a home tank) and the dragon goby.
The clown knife is fine alone, he needs a hiding spot though.
The mollies will be very happy together.
Please do more research and talk to the employees of the place you get your fish. They had to have told you all this, or they would have if you had asked.
Please get a book.

EDIT
Ray ray is an idiot. Don't listen to the first 2 answers, they have no idea what they are talking about.
They definately will eat each other eventually if they get hungry watch out for the mollys and the silver tipped shark.
If there are alot of good hiding spots you should be good and keep you light on. The gourami are the ones to watch they are passive and may be attacked
With an 80 gallon, you have a little more wiggle room, especially if you have adequate plant cover. I would be most concerned for the clown knife because even though they can get quite large, they are generally pretty passive and don't move very quickly (making them an easy target for you gourami and large mollies). The glass fish may also be a target--they are generally pretty passive as well. Watch them to see if any appear to be aggressive towards the others. Also look for shredded tails or red spots on any of the fish. Often you won't notice any of the fish being aggressive because they will do it at night. If you start to see signs, you should take the fish out immediately. If you don't have a lot of tank decorations or plants now, it might be a good idea to add some--this might keep problems from starting.
Yep, well almost. They are all community fish and should be ok considering the size of the tank. The problem here is that these are all school fish excluding the gourami which are just dirty fish and I would give them the flush or put them in a goldfish bowl or somthing.. Anyway these schooling fish need friends of their own kind, it will reduce stress and fighting amongst the other fish.. The idiot who sold you the fish should have told you this. I woud go back to the store and get at least two more of each fish or take some back and replace with like fish in the tank.. Mollies have a tendency to be agressive, espically if in a tank without any buddies.. Good Luck and there is alot of help out here in cyber space. Surf around a bit
Err no i wouldnt have thought so, i fort u were chattin bout goldfisheis @ firstbut obviously not, no they would not go well together in the end there would only be one left (the one that aint bin eaten !)
I would watch the gouramis and the shark and the goby. See how they get along. Different fish even of the same type get along differently. Gouramis can get mean to each other and to the pacu. Also, that pacu can be kinda big when full grown and might get hunger pains you might say.
The answer is probably, with exception to the pacu (and no they are not carnivores lie pirahnnas as mentioned above. One of the major differences between the two is that the pacu is primarily vegetarian). The pacu will grow to be HUGE though and will need a much larger tank than an 80 gallon. My understanding is that these fish can grow to over two feet commonly.
No they all have different needs.
Clown Knife and Mollies can work together they both need hard water.
Dragon Goby needs really clean water and it too needs to be hard, although the Mollies might beat up on them
Blue Gouramis need to be in a group with soft to med water.
Silver tipped also needs a group but with medium water. And the same for the Kissing gourami
And the Pacu will eat everything sonner or later
OMG OMG OMG you need to seperate them NOW! Hurry.. before they eat each other!.
if you buy them when they are all small it might work
Surprisingly enough, watch out for the gouramis they can be nasty. The clown knife might eat another fish if it fits in his mouth. And the pacu will probably eat his tank mates eventually.
You have a mixture of semi-aggressive and non-aggressive tropical fish.

The pacu is going to become very large - and he'll eat whatever will fit in his mouth. They are quite similar to Oscars and they are related to the piranha family.

The mollies should be okay - the are nonaggressive but I've seen them stand up for themselves. They become 3 inches when full grown, I think they will be big enough to not be eaten.

The poor glass fish isn't going to get very large, and he isn't going to defend himself. I don't think he will make it in the long run. Plus he is a schooling fish, so he really should be with two other glass fish. Schooling fish do best in groups on 3 or more.

It's good that you have a large tank. And I imagine they are all pretty young right now, so it's also good that they are growing up together. You shouldn't have many problems - but if you do add more fish I would stick with the semi-agressive since that's what you mainly have.

Also, fish do best in pairs. So if you do plan on getting more fish I'd get another kissing fish, gourami and a shark. The pacu and knife and goby should all be fine alone.

Good luck!


PS: Pacu's are mainly vegetarians, but they DO eat small fish. We would randomly place small guppy feeders in the pacu tank at the fish store and they would all fight over it until it was swallowed.


EDIT:

"I don't know about the silver tipped shark (never heard of them in a home tank) and the dragon goby."

A silver tipped shark is really a catfish. It's called a shark for sales. It's semi-agressive, and will eat small fish. Get's to be, I believe 12 inches long. It's a popular fish because people think it's a shark.

The dragon goby is semiagressive fish as well. But they usually keep to themselves. They are very sensitive and can be hard to keep alive, esp in new tanks. They can get large as well.
The pacu will become a problem, they are in the pirhana family, fin nippers.
yes as long as they are community fish
