As an apartment dweller, I would highly recommend Raid Max Roach Bait Plus Egg Stoppers.
The poisoned bait stations kill the roaches you have, and the egg stopper cartridges contain an insect hormone that prevents female roaches from reproducing. You need to give the product about six weeks to completely eradicate the roaches, but it really works!
In the meantime, make life as uncomfortable for the roaches as possible.
Eliminate their food supply - seal ALL food in ziplock bags or tupperware containers, seal up all pet food, keep pet cages/beds/litterboxes clean, rinse dishes promptly, dispose of trash regularly
Limit their water supply - tighten all faucets and fix leaks, insulate cold water pipes to prevent condensation, empty refrigerator/
AC/dehumidifier drip trays often
Eliminate nesting places - reduce clutter, discard cardboard/newspaper/brown grocery bags, seal up cracks and crevices, seal up electrical outlet/switch covers
If this doesn't work (very unlikely unless you have a major infestation), contact an exterminator. I would stay away from the do-it-yourself foggers and leave the application of pesticides to the pros. They shouldn't have to spray anywhere near your fish unless you have tanks in the BR and kitchen like me!
