Hi guys,
I'm new to the hobby and new to the forum. I've been reading fishlore regularly as I have been researching my tank. I initially wanted to do oscars, but when I figured out I would need at least a 55g for one oscar, I started looking at other options. I live on the second floor of a really old building. I plan to buy a place in less than five years, and I will be upgrading to a 75+ tank.
For now, I've got a 37g tank (it's the same footprint as a 29 but taller). I set it up yesterday, and it is still cycling. Today I added two swordtails as a source of ammonia for the nitrogen cycle. I'm not overly concerned with their well being. Matter of fact, they may end up as feeders depending on the fish I get.
What would be a good setup for this tank? I have a couple of ideas. Maybe some experts can give me some advice. The only thing I don't want is a boring old tetra community tank. I want some fish with a little aggression. I also think it would be cool to watch cichlids raise some kids.
I've included a couple of pics:
1. Angels and Dwarf Gouramis
2-4 angels
2-4 dwarf gouramis
1-2 plecos
2. Red Bellied Piranhas
3-4 baby (quarter size) RB piranhas
3. Convicts, Firemouths, or Blue Acaras, severums
2-4 of any of the above cichlids
1 pleco
4. 1 big ol' cichlid
1 jack dempsey, green/red terror, jaguar
Any advice would be greatly appreciated.

Thanks,
-C
