does this mean my blue gourami...uhh.....welll.....not suited for my 90 gallon? kinda worried now...........
gallons: 90
stats: i dont have a kit.....sry and im not going to petsmart to get it checked in a while.......
width: 18 inches
lenght: 48 inches
height: 23 1/2 inches
aquariums stock: 1 black ghost knifefish, 1 peacock eel, 3 buenos aires tetras, 2 dalmation mollies, 1 dwarf gourami, 1 honey gourami, 4 cory catfish,
1 redtail shark, 1 longfin rosey barb, 1 red lyertail, 1 pictus catfish.
set up: some plants, lots and lots of hiding places including 4 tubes, 2 aquarium decor tunnels, another viney wood decoration thing, and a.......rock.
i hope this setup is ok!
Buenos Aires Tetras are quite nippy fish so i wouldn't recommend keeping them with gourami's which are vulnerable to having their feelers nipped. The tetras are also shoaling fish so should also be keept in shoals of 5-6+ (larger considering the size of your tank). Kept in numbers too small they will be constantly stressed or may develop anti-social behavior- this goes for all shoaling fish.
Black Ghost Knife are predatory fish so will probably eat the smaller fish in the tank when its large enough. The tank is a bit on the small side width-wise for a ghost knife in the long term (ideally the tank should be at least 24inches wide instead of 18inches wide);

Peacock spiny eel: Being predators they should only be combined with fish that are over 3", smaller fish will be eaten;

Pictus catfish are also predators and shouldn't be kept with fish under 3inches;

Mollies are sociable fish and prolific livebearing breeders. Gender ratios are very important as males can overly harrass females if there aren't enough, while the males can be aggressive towards one another if not in the right numbers etc. So a lot depends on whether your 2 are male or female. Either way they are 1 too few and in a tank with a few predatory fish...
Same goes for the Lyretail Swordtail. Livebearing fish, sociable, though keeping more than one male in a group of females is trickier than with other livebearers etc.
Red Tail Black Sharks are semi-aggressive territorial fish. As to how aggressive or territorial they are depends on the individual fish (while juveniles they're usually not too bad, but they become worse with age) and the habitat/environment they're kept in the tank. They are tricky to keep well in community tanks when it comes to the happiness of the other fish as RTBS often go for fish with distinctive tail markings or colouring similar to their own (so avoid red or black or red & black fish) etc. They shouldn't really be kept with fish that are too slow (like gouramis) to defend themselves against the RTBS. A tank full of small quick tetras, danios or barbs etc makes a better community option for RTBS.
Really your tank is a real odd selection. You should really do more research on fish before getting them as all of this could have been avoided with more research (don't listen to what pet shop/LFS staff say as they often don't know what they're talking about- use good books, internet sites or seek advice from experienced good fish keepers instead etc). Their is a good fish species index on the forum with lots of information on all sorts of fish;

A great deal of the fish you have cannot be kept together or are not suited to each other. You need to choose between either;
a. A tank with a few large fish, with the predatory fish being the main focus. You cannot keep lots of small fish with such predatory fish as sooner or later they will eat or attack them.
b. A peaceful planted tank set up with the gourami's as the focus & some peaceful fish (ones which won't nip/harrass or stress the gourami's etc). Corys, khuli loaches, peaceful tetras & barbs, peaceful livebearers like guppys or female mollies etc would make good tank makes.
c. A robust community tank with the Red Tail Black Shark & Buenos Aires Tetras as the focus- good tank mates would include other quick robust shoaling fish like danios or harlequin tetras, and robust bottom fish like Yoyo/Pakistani Loaches.
Your tank has a lot of fish compatability issues so you really need to sort this out now rather than later. You can either rehome the incompatible fish or set up other (suitably sized) tanks for them
