Cool! Saving money on test kits!! Woot!!! $100 will get you a some fish. Blue reef chromis around here are around $7-8 each, 3 would be a great number of those, and they're very active swimmers and a beautiful color blue. Not all SW
fish are expensive. A orange oscellaris clown is about $20. There are some fish that are $20 and less. Firefish are cute and inexpensive, usually
$15 or less for the white/red ones. And you don't have to add all the fish at once- do one every month or two until you get stocked.
