Colisa fasciata is also known as the 'striped' gourami and, more commonly, the 'giant' gourami. These fish get to about 4" max so are the largest of their genus (hence the name), with males turning out slightly larger, though slimmer, than females. Males are also considerably more brightly colored and have longer fins and a more pointed dorsal and anal fin. Behaviour-wise they are much like any other gourami in the genus colisa. They are relatively peaceful but, males can become aggressive if crowded as they are still territorial fish. They do best kept in a ratio of 2 females per male but 2 males or females or a male/female pair will also co-exist quite happily as long as the tank is a suitable size to make up for any male-female chasing or territorial aggression. Females like to have company, males do fine alone. They appreciate floating plants for cover and, like related gouramies, will choose a territory in the upper layers if given that option. They do need to breathe air so care should be taken to make shure they do have access to it and can get to it without being harassed or bullied. In many ways they are extremely similar in character to the common dwarf gourami (colisa lalia) but banded gouramies are a lot hardier and much more resistant to disease. They are also, IME, more active and out-going though they can be rather shy when not yet settled in. Feeding should not be an issue - neither should pH or hardness - but do try to provide a little vegetable matter in the diet and live/frozen daphnia, brine shrimp, bloodworms etc will all help bring out color and encourage breeding behaviour. Like any other fish, good water quality is vital and, like many other gouramies, fluctuations won't be appreciated. They do like higher temperatures of around 79 deg F and should get along with most peaceful to semi-boisterous but non-nippy fish. If you have a male/female pair and ever wish to breed them, just follow the same steps as you would take with a dwarf or honey gourami as they are pretty much the same as far as breeding patterns/behaviour is concerned. If you can't find info for this fish under its common name(s), try the scientific name. As I've said, most info on dwarf or honey gouramies (which is plentiful on the net) is also relevant as long as you take into acount the size difference.
Also at the LFS they had them listed as Indian Gourami....
Any ideas?
He is perfectly happy and healthy tho. 
Anyway, i have explained to the lfs what he has, and they have put him into in isolation tank on his own, and will medicate him
