Well you can keep plants with angels but not cichlids, yes angels are cichlids but they don't destroy plants like the others do. If you want to get into bright colored fish you should check out Africans. You don't have a huge tank so I would not get into central Americans. Angels get really big and beautiful. I would stock the 29 gallon with a couple angels, maybe three and the 36 gallon with Africans. The like lots of rockwork, so if you get into them I would get some rocks so they can hide in.
Are you familiar with the cycling process? If not then we will help you. You can’t just get a bunch of fish and put them in, they will die from the cycling process.
If you don’t have a python and hose I would get one. They attach to your sink and suck up the crud at the bottom of the tank. Then you just fill it back up with water from the sink, use a dechlorinator. If not your fish will get sick from chlorine poisoning. But the python and hose saves you from the bucket method which really hurts your back and it’s quicker.
Once your tank is cycled you should clean it every couple of weeks. Feed them twice a day but not a lot, don’t dump the whole can in, lol.
One more thing, never clean your filter media with tap water, gently rinse it with tank water, it has all your good bacteria on it and you will destroy it causing a mini cycle.
