Hi..just me again....
Before you add any fish to this new tank..make sure you have it completely "cycled' first.
It may take around a month before all your water parameters read what they should.
ZERO ammonia...
zero nitrites..and your NitrAtes should always stay below 20.
To jump start your cycle...there is a product called
Bio-Spira that will give you the benefical bacteria needed to balance your sysytem & have a healthy environment for your fishies. If you add that..you can place the fish in right away.
If you can't find that product...ask your LFS if perhaps they would give you a scoop of gravel from an established tank. About a cup should do it. Place that is a nylon sock in the corner. ( don't rinse the gravel or anything). I know we used to do that to help people out..especially if you are buying fish from them.
You were asking about some colorful fish? Yes..I think the african cichlids would probably be great for you. ( Check out my post w/ video of my african tank)
If you went with Yellow Labs...
in a 30 gal. you could probable have one male and a few females.
Other Mbuna's ( or Lake Malawi) cichlids would be compatible with them as well.
Africans ( as do most fish) prefer more subdued lighting. It just makes them feel more secure IMO. I have a flourscent on my 75 gal..which is probably around 100 watts. Just the one strip. It is bright enough to see the fish & their colors.
But this is your tank...
it's what you like best.

* BTW..like your user name...
